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

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!
