a.No

b.-7/2, it is at (4,-7/2)

c.-5?4, it is at (2,-5/4)

d.All real numbers except 6

e.3

f.-1/2

Step-by-step explanation:

a. Plug it in! f(5)=((5)+3)/((5)-6)=-8, so no!

b. Plug it in! f(4)=((4)+3)/((4)-6)=-7/2

c. Plug it in! f(2)=((2)+3)/((2)-6)=-5/4

d. If it were to be 6, then it would be 3/0 which would be undefined.

d.f(-3)=((-3)+3)/((-3)-6))=0/8

f.f(0)=((0)+3)/((0)-6)=-1/2

true
