Question

What is the range of the function f(x) = (x – 1)2 when the domain is {-5, 0, 5}?

Answer 1

9514 1404 393

Answer:

{1, 16, 36}

Explanation:

Put the numbers in for x and see what the f(x)-values are.

(-5-1)^2 = (-6)^2 = 36

(0-1)^2 = (-1)^2 = 1

(5-1)^2 = 4^2 = 16

The range is the set of values {1, 16, 36}.
