Question 694358: I need help on this partical question. Then i will be able to slove the rest of the problems. Here's the problem. "f(x)= 2x+2;{-1,0,1,2,3}. The question is to find the range of each function for the given domain. Please help.

You can put this solution on YOUR website!
f%28x%29=+2x%2B2 with domain = {-1,0,1,2,3}
(Those are the values of x where the function is defined
The range is the set of values for f%28x%29 for the x values in the domain.
f%28-1%29=+2%28-1%29%2B2=-2%2B2=0
f%280%29=+2%280%29%2B2=0%2B2=2
f%281%29=+2%281%29%2B2=2%2B2=4
f%282%29=+2%282%29%2B2=4%2B2=6
f%283%29=+2%283%29%2B2=6%2B2=8

Range = {0,2,4,6,8}
