Question

What is the range of the function f(x) = 3x − 12 for the domain {-2, 2}?

Answer 1

domain = x values
range = y values
so substitute x for given domain then solve for f(x) (which is same as y)

Answer 2

Answer 3

Have you tried doing what Nnesha told?

Answer 4

@americansniper12 can u help

Answer 5

The range is the y values. So you need to insert x=-2 and x=2 in your equation. Then you get the range.

Answer 6

I ended up with (-6,-18)

Answer 7

\[f(-2)=3*(-2)-12=?\] \[f(2)=3*2-12=?\]

Answer 8

Yes, so that is your range, in the given interval :)
