Question

What is the range of the function f(x) = 3.2x for the domain {-4, -2, 0, 2, 4}?

A) {-12.8, -6.4, 0, 6.4, 12.8}



B) {12.8, 5.5, 0, -6.4, -12.8}



C) {0, 6.4, 12.8, 19.2, 25.6}



D) {-12, -6, 0, 6, 12}

Answer 1

Answer: A) {-12.8, -6.4, 0, 6.4, 12.8}

Answer 2

the range is the values of y, or the values of f(x)
multiple every number in the { } by 3.2, you will get the range.
the answer is A
