Given the function f:x → 3x + 1 and g: 2x, fg(x) is:
6x² + 1.
6x+2.
6x + 1.
6x.
For any function f, f⁻¹ always maps its:
Image to the range.
Range to its domain.
Domain to its range.
Domain to its codomain.
The figure is a quadratic graph of y = f(x).
The solution of f(x) = 0 is/are:
-1 and 3.
1 and -3.
3.
1.
The inverse of the function f(x) = 3x is:
3/x.
3x/2.
2/3x.
x/3.
The mapping represented in the figure is:
1 – many.
1 – 1.
Many – 1.
Many – Many.
