Using the parent function, f(x)

a) Reflect the graph about the x-axis.
b)Vertical compress by a factor of 13 .
c) Vertical shift up 2.
d) Horizontal shift right 3.
Answers
The graphs of the transformed functions are below, the colors are:
a) g(x) = -x^2 → green.
b) g(x) = x^2/13 → blue
c) g(x) = x^2 + 2 → orange
d) g(x) = (x - 3)^2 → purple.
How to graph the transformed functions?Here we have the quadratic parent function:
f(x) = x^2
And we want to apply some transformations, and then graph them.
The transformations are:
a) "Reflect the graph about the x-axis."
This is written as:
g(x) = -f(x)
Replacing f(x) by the actual function:
g(x) = -x^2
b) "Vertical compress by a factor of 13"
This is written as:
g(x) = f(x)/13 = x^2/13
c) "Vertical shift up 2."
This is written as:
g(x) = f(x) +2 = x^2 + 2
d) "Horizontal shift right 3."
This is written as:
g(x) = f(x - 3) = (x - 3)^2
The graphs are below, the colors are:
a) g(x) = -x^2 → green.
b) g(x) = x^2/13 → blue
c) g(x) = x^2 + 2 → orange
d) g(x) = (x - 3)^2 → purple.

What is the range of the function f(x) = 4x – 5 over the interval of 1 < x ≤ 5? Give your answer in interval notation.
Answers
Answer:
Hello,
Step-by-step explanation:
[tex]1 < x\leq 5 \ \\\Longrightarrow\ 4 < 4x \leq 20 \ \\\Longrightarrow\ -1 < 4x-5 \leq 15 \\\Longrightarrow\ -1 < f(x) \leq 15 \\\\range=]-1; 15][/tex]
The range of the function f(x) = 4x - 5 will range from -1 to 15.
What are the function and range?The expression that established the relationship between the dependent variable and independent variable is referred to as a function. In the function as the value of the independent variable varies the value of the dependent variable also varies.
A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Given that the function f(x) = 4x – 5 and the interval is 1 < x ≤ 5. The range will be calculated as,
1 < x ≤ 5
4 < 4x ≤ 20
4-5<4x - 5< 20-5
-1 < 4x - 5 < 15
Therefore, the range of the function f(x) = 4x - 5 will range from -1 to 15.

The polynomial function with degree 5 is formed as:

What are termed as the polynomial functions?Polynomials are algebraic representations that contain indeterminates and constants.A polynomial is an algebraic expression in which all of the variable exponents have become whole numbers.Any polynomial's variable exponents must be non-negative integers.A polynomial's degree is the highest and greatest exponent of a variable in such a polynomial.The degree is used to approximate the optimal number of solutions to a polynomial function using Descartes' Rule of Signs.(-2) is derived from the factor (x + 2); because it has a multiplicity of three, you must account for that zero three times; thus, it is composed as (x + 2)³.
0 is derived from the factor x.
2 is derived from of the factor (x - 2).

A. d = 13/3 miles.
B. d = 4.25 miles.
C. d = M x 5/60(first five minutes) + N x 15/60(last 15 minutes).
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
Hence the distance is:
d = vt.
In item a, considering the time in hours, we have that:
v = 13, t = 20/60 = 1/3.
Hence:
d = 13/3 miles.
In item b, we have different definitions, then:
d = 15 x 5/60(first five minutes) + 12 x 15/60(last 15 minutes).
d = 15/12 + 15/5
d = 4.25 miles.

The 5000 that invested in Fund A returned a 3% profit. The amount that invested in Fund B returned a 10% profit. How much did she invest in Fund B, if both funds together returned a 5% profit?
Answers
The investment in Fund B is $2000.
To understand the given question we first have to understand the logic of percentage and how it affect the return on Investment.
If an investment fund returns a profit on an investment then the profit is calculated by multiplying the investment with the profit(in decimal form).
For Example: If the investment is A and profit is x % then the profit is calculated by:
Profit =A×([tex]\frac{x}{100}[/tex])
Now in the given problem, let us consider the amount of investment into the Fund B be x.
Profit in Fund B=10%
Profit in Fund A is 3%.
Investment in Fund A=$5000
Total profit from both investments=3% of 5000+10% of x
[tex]=\frac{3}{100}\times 5000 + \frac{10}{100}\times x\\ =150+0.1x[/tex]
Now the total investment=5000+x
The combined profit for both the Investments is 150+0.1x
But the combined profit is 5% for both investments.
profit=[tex]5\% of(5000+x)[/tex]
[tex]=\frac{5}{100}\times (5000+x)\\=0.05\times5000+0.05x\\=250+0.05x[/tex]
Now the profit is same, so if we equate both the expressions of profit we get a linear equation in x.
[tex]\therefore 250+0.05x=150+0.1x\\or,250-150=0.1x-0.05x\\or,100=0.05x\\or,x=2000[/tex]
Thus we can conclude that she invested $2000 in the Fund B.

evaporation is 2.35 inches how many gallons of water must be added to the pool if it does not rain? If during the next week the pool still loses two. 35 inches of water to evaporation, even with 20 mm of rainfall, how many liters of water must be added?
Answers
Answer:
946 gal
629 gal
Step-by-step explanation:
volume that evaporates = LWH
volume = (5.0 m × 100 cm/m × inch / 2.54 cm) × (12.0 m × 100 cm/m × inch / 2.54 cm) × 2.35 inch
volume = 218,550 in.³
volume = 218,550 in.³ × 1 gal / 231 in.³
volume = 946 gallons
You must add 946 gallons.
The loss to evaporation is 2.35 in.
The amount of rain is 20 mm
The net loss is
2.35 in. × 25.4 mm / inch - 20 mm = 39.69 mm
39.69 mm × 1 inch / 25.4 mm = 1.563 in.
The net loss now is 1.563 in. instead of 2.35 in.
We find the fraction of the the previous loss is the loss with rain and multiply by the previous loss.
1.563/2.35 × 946 gal = 629 gal
With rain, then 629 gallons of water must be added.
