Given the function f(x) = x2 − 5x − 6 the value of f(2) is:
0.
12.
-12.
20.
The arrow diagram in the figure shows the relationship between M and N.
The domain is:
{1, 4, 3, 8, 16}.
{1, 4, 9, 8, 16}.
{1, 2, 3, 4}.
{1, 4, 9, 16}.
For any function f, f⁻¹ always maps its:
Domain to its range.
Domain to its codomain.
Range to its domain.
Image to the range.

7.
-5.
-7.
5.
Given the function f: x ⟼ 2x − 3, the inverse function is:
(x - 2)/2.
3x/2.
