The table below shows the fourth powers of different numbers:
Number (x) 1 1 2 2
Fourth Power of the number (y) 1 1 16 16
Part 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 truck for x hours is shown below:
f(x) = 17x + 50
What is the value of f(30) and what does f(30) represent? (5 points)

unowen
A) y does represent a function of x, as in the equation y=f(x)=x^4
B) If f(x)=17x+50, then f(30)=17(30)+50=560. f(30) represents the cost of renting a truck for 30 hours.
