Question

The domain of the function f(x)=3x³ is {2,5}. what is the functions range?

Answer 1

That is not correct ^

Answer 2

Range: {24, 375}
If the domain of the function is limited to 2 and 5, you plug in those x-values to calculate their corresponding y-coordinates.

f(2) = 24 and f(5) = 375.

2^3 = 8
3 x 8 = 24

5^3 = 125
3 x 125 = 375

That means the range is {24, 375}.
