Question

How do you find the range of each function given the domain: `g(m)=m^2; {-2,0,2}`?

Answer 1

The set of numbers `y` such that `0 <= y <= 4`

Explanation:

For this one, all you have to do is plug some numbers in.
If `m = 0`, then `y = g(m) = 0`.

`y = g(m)` is always `>=0`, becase if `m` is negative, `m^2` is positive.

At m = -2 and 2, `y = g(m) = 4`. For y to be greater than 4, m would have to be greater than 2 (or less than -2).

So your range is between 0 and 4, inclusive.

GOOD LUCK!
