The domain is the numbers you can use for x
so the domain is 4
the range is the possible y values we get from that domain
we get all real numbers because it goes up and down infinitey
domain is 4
range is all real numbers
x/10 + x/4 = 21 /*40
4x + 10x = 840
14x = 840
x = 60 = total number of points the team scored
The correct answer is C.) (y|y > -4).
In order to find the range, we look for the possible numbers that y can be. In this case, you'll see the lowest the number goes is -4 and it continues up forever. Therefore, the answer is that y has to be greater than -4.
