Given the function, f(x) = 1 - 2x. The value of f(-3) is:
5.
-7.
7.
-5.
Given the mapping in the figure, the range set is:
{1, 2, 3, 4}
{1, 2, 5, 5, 8}
{2, 3, 5}
{2, 5, 8}.
Given the function f:x → 3x + 1 and g: 2x, fg(x) is:
6x² + 1.
6x+2.
6x.
6x + 1.
The figure is an arrow diagram of a relation between P and Q. The range of the relation is:
{a, b, c}.
{1,2,3,4,5).
{1, 3, 4}.
{2,5).
For any function f, f⁻¹ always maps its:
Range to its domain.
Domain to its range.
Domain to its codomain.
Image to the range.
