Question

Help!!!!!

The table below shows the cube roots of different numbers:

Number (x) 27 -27 125 -125
Cube root of the number (y): 3 -3 5 -5

Part A: Does the table represent y as a function of x? Justify your answer.

Part B: The total cost f(x), in dollars, for renting a house for x months is shown below:
f(x)=925x+1000

What is the value of f(24) and what does f(24) represent?

Answer 1

For each input (number), there is exactly ONE output. So the given table does represent a function.


If f(x)=925x+1000 and x=24, then f(24) = 925(24)+1000 = 23200.
