Question

function f(x) = -2x2, if the domain is {-3, 0, 3}, find the range

Answer 1

plug in each value in the domain to get corresponding values in the range

Answer 2

so for instance, if x = -3, then..

f(x) = -2x^2

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

f(-3) = -2(9)

f(-3) = -18

Answer 3

So x = -3 in the domain corresponds to y = -18 in the range

Answer 4

Do this for every value in the domain to build the complete range for this function (and restrictions)
