Question

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


{-12.8, -6.4, 0, 6.4, 12.8}



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



{0, 6.4, 12.8, 19.2, 25.6}



{-12, -6, 0, 6, 12}

Answer 1

Just sub in each value for x in the equation provided to find the corresponding value for y. That will be your range!

Answer 2

HINT: You only need to do it once to find the answer :)

Answer 3

this is kinda my weak point
