Domain is the set of x values:{-2,-1,-0,1,2)
The range is the set of y values generated from the set of x values.
f%28-2%29=2%5E%28-2%29=1%2F2%5E2=1%2F4
f%28-1%29=2%5E%28-1%29=1%2F2%5E1=1%2F2
f%280%29=2%5E%280%29=1
f%281%29=2%5E%281%29=2%5E1=2
f%282%29=2%5E%282%29=2%5E2=4
So, the range is :{1/4,1/2,1,2,4}
