Question

find the range of the function

G: x --> x^2-4x+4; Domain= {0, 1, 2, 3}

Answer 1

Because the domain is four distinct integers, and not any numbers in between, we must figure out the solution to each number in the domain to find the range.

0^2-4(0)+4=4
1^2-4(1)+4=1
2^2-4(2)+4=0
3^2-4(3)+4=1
The range is {0,1,4}, the only possible outputs.
