Question

What is the range of the function f(x)=x2−3 when the domain is {1, 3, 5}?

Answer 1

the range is {-2, 6, 22}

Explanation:

Use " ^ " to indicate exponentiation: f(x) = x^2 - 3.

For each value in the domain {1, 3, 5}, calculate f(x) = x^2 - 3:

f(1) = 1^2 - 3 = -2

f(3) = 3^2 - 3 = 9 - 3 = 6

f(5) = 5^2 - 3 = 25 - 3 = 22

Thus, the range is {-2, 6, 22}
