Question

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

Answer 1

The range are all the possible solutions for y. Since the domain is given, these are all the possible x values. To find the range, we can simply substitute each of these x values to the given function f(x) = 3.2x.

Given the domain, we use this to find the range values,
Domain: {-4, -2, 0, 2, 4}
Range: {-12.8, -6.4, 0, 6.4, 12.8}
