Answer 1

For every x value, y=the squares value of said number. The equation of said values is y=x^2. The value for plunging in 150 for x=470, and f(150) represents the total cost of renting the boat for 150 hours.

Answer 2

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

Yes, this table does represent y as a function of x. No x-value appears more than once, and in each case, there is exactly ONE associated y-value. Were there more than one associated y-value, the table would not represent a function.

****************

f(x) = 20 + 3x

What is the value of f(150), and what does f(150) represent?

Substitute 150 for x (in two instances) in the given function:

f(150) = 20 + 3(150) = 20 + 450 = 470. This is the value of the function when the input value (x) is 150 units.

f(150) is functional notation represents the value (y-value) of the function when the input (x-value) is 150 units.
