f(x) and g(x) are both functions with Domains and Codomains all positive Reals.

f(x) = 2x² and g(x) = 4x - 1. If f(g(x) = 8, what is x?

a	2
b	1/2
c	3/4
d	None of the above

____________________________

If f(x) = 7x + 3 and g(x) = 4 - x³, then what is g(f(-2))?

a	87
b	1335
c	12
d	-13

___________________________________

Let R be the relation from A to B, where A = {1,2,3} and B = { 5,6,7,8}

R = {(1,6), (2, 8), (3, 7), (2,6)}

Remove one ordered pair so that R will be a function from A to B.

a	Remove(1,6)
b	Remove (3,7)
c	Don't remove anything R is already a function.
d	Remove either (2,8) or 2,6)
