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

Hello there!

The function is f(x) = 3.2*x and we want to know the range of this function for the domain (-4, -2, 0 , 2, 4)

First we need to evaluate f(x) in the points of the domain, and this give us the pairs:

(-4, 3.2*-4) = (-4, -12.8)

(-2, 3.2*-2) = (2, -6.4)

(0, 3.0) = (0,0)

(2, 3.2*2) = (2, 6.4)

(4, 3.2*4) = (4, 12.8)

The range is the codomain or image of the function, then the range of f(x) for the given domain is:

(-12.8, -6.4, 0, 6.4, 12.8)

50=33x+22
