f(x) and g(x) are both functions with Domains and Codomains allpositive 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 isg(f(-2))?

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 toB.
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) |
