Question

What is the range of the function f(x) = 2x-5?

Answer 1

the range is all your y values once you plug in values for the equation for example maybe you choose to use 0,1,2,3 as your x values. Now you have to plug each one of these values in.
f(x)=2(0)-5
f(x)= -5
f(x)=2(1)-5
f(x)=-3
f(x)= 2(2)-5
f(x)=-1
f(x)= 2(3)-5
f(x)=1
so -5,-3,-1 are your y values when x is 0,1,2, and 3
your y values are your range and your x values are your domain
