PartB needs to be solved.The table below shows the fourth powers of different numbers:Number (x) 1,-1,3,-3Fourth power of the number (y) 1,1,81,81Part A: Does the table represent y as a function of x? Justify your answer. (5 points)Part B: The total cost f(x), in dollars, for renting a townhouse for x months is shown below:f(x) = 875x + 750What is the value of f(12) and what does f(12) represent? (5 points)

Answer 1

Given:

$f(x)=875x+750$

To find:

The value of f(12).

Explanation:

Substituting x = 12 we get

$\begin{gathered} f(12)=875(12)+750 \\ =11250 \end{gathered}$

That means,

The total cost for renting a townhouse for 12 months is $11250.

Where f(12) represents the total cost of renting a townhouse for 12 months.

Final answer:

• The value is,

$f(12)=11250$

• The value f(12) represents the total cost of renting a townhouse for 12 months.

That is, the total cost for 12 months is $11250.
