Question 52307
a. There is nothing that x is not allowed to be in this function, so the domain is all real numbers.
b. g(x)=2x-1
g(-1)=2(-1)-1
g(-1)=-2-1
g(-1)=-3
g(2)=2(2)-1
g(2)=4-1
g(2)=3
c. When the horizontal value (x) is -1, the vertical value (g(x) or y) is -3.
When the horizontal value (x) is 2, the vertical value (g(x) or y) is 3.
