The following function represents the value of a house, in dollars, after x years:f(x) = 242,000(1.04)x
What does 242,000 represent?
The present value of the house
The value of the house after x years
The increase in the value of the house each year
The increase in the value of the house after x years
Answers
Answer: The present value of the house
Step-by-step explanation:
Given: The following function represents the value of a house, in dollars, after x years:
When we substitute x=0 in the above equation, we get
Since at x=0, the function represent the initial value of a function.
Therefore, 242,000 represents the value of house in 0 years i.e. it represents the present value of the house.

The zeros of a function are the values of x that equates the function to 0
The zeros of the function are: 0, -7 and -2
The function is given as:
Equate to 0
Cross multiply
Split
Solve for x
Hence, the zeros of the function are:
F. 0
D. -7
C. -2

question: What are the zeros of the function below? Check all that apply.
F(x)= x(x+7)(x+2) / (x-4)(x+4)
answer:
- c. -2
- d. -7
- f. 0
explanation: The "0" you are looking for are the x's. They equal the F(x) to 0.
F(x)= x(x+7)(x+2) / (x-4)(x+4)
Step 1- Set equal to 0.
- x(x+7)(x+2) / (x-4)(x+4) = 0
Step 2- Multiply.
- x(x+7)(x+2) = 0
Step 3- Separate.
- x = 0
- (x+7) = 0
- (x+2) = 0
Step 4-Simplify.
- x = 0
- x + 7 = 0
- subtract 7 from both sides.
- x = -7
- x + 2 = 0
- subtract 2 from both sides.
- x = -2
summary: The zeros in the function F(x)= x(x+7)(x+2) / (x-4)(x+4) are 0 , -7 , or -2.

REASON: x represents the number of movies and if each movie is 2.50, then 2.50x will tell u what u paid for the movies, but u cant forget the monthly service fee of 5.75. So lets say u rent 5 movies, 2.50(5) + 5.75 = 12.50 + 5.75 = 18.25, so u would have spend 18.75 for the month
