Given the function f:x → 3x + 1 and g: 2x, fg(x) is:
6x+2.
6x.
6x² + 1.
6x + 1.
Given the function f: x ⟼ 2x − 3, the inverse function is:
(x - 3)/2.
3x/2.
(x - 2)/2.
(x + 3)/2.
Given that f(x) = x and g(x) = 3x - 2, then the composite function gf(x) is:
3x - 2.
(x + 2) / 3.
(x - 2) / 3.
3x² - 2x.
Given the function f(x) = x2 − 5x − 6 the value of f(2) is:
20.
0.
12.
-12.
For any function f, f⁻¹ always maps its:
Range to its domain.
Image to the range.
Domain to its range.
Domain to its codomain.
