The inverse of the function f(x) = 3x is:
3/x.
3x/2.
x/3.
2/3x.
The arrow diagram in the figure shows the relationship between M and N.
The domain is:
{1, 4, 9, 16}.
{1, 4, 3, 8, 16}.
{1, 2, 3, 4}.
{1, 4, 9, 8, 16}.
Given the function, f(x) = 1 - 2x. The value of f(-3) is:
5.
-5.
7.
-7.
Given the mapping in the figure, the range set is:
{2, 5, 8}.
{2, 3, 5}
{1, 2, 5, 5, 8}
{1, 2, 3, 4}
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.
