The inverse of the function f(x) = 3x is:
3/x.
x/3.
3x/2.
2/3x.
The figure is a quadratic graph of y = f(x).
The solution of f(x) = 0 is/are:
3.
1.
1 and -3.
-1 and 3.
Given the mapping in the figure, the range set is:
{2, 3, 5}
{1, 2, 5, 5, 8}
{2, 5, 8}.
{1, 2, 3, 4}
The mapping represented in the figure is:
1 – 1.
Many – 1.
1 – many.
Many – Many.
The point (5, 4) when reflected in the line x = y. has image
(-5, -3).
(2, 3).
(3, 5).
(5, 5).
