ALGEBRA HELP #1

posted by .

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)

  • ALGEBRA HELP #1 -

    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.
