The inverse of the function f(x) = 3x is:
2/3x.
3x/2.
x/3.
3/x.
Given that f(x) = 3 - 2x, then, f(-1) gives:
6.
5.
1.
-1.
Given the function, f(x) = 1 - 2x. The value of f(-3) is:
-5.
-7.
7.
The figure shows a relation from set A to set B.
The range of the relation is:
{ (a,1), (b,1), (c,4), (d,2) }
{1, 2, 3, 4, 5}
{a, b, c, d}
{1, 2, 4}
The point (5, 4) when reflected in the line x = y. has image
(3, 5).
(2, 3).
(5, 5).
(-5, -3).
