Question

The one-to-one functions g and h are defined as follows. g = {(24), (4, 2), (5,-1), (8, -9) h x) 8x+13 Find the following. g (4) =

Answer 1

The value of g(4) is 2.

Explanation:

Given,

The one-to-one functions g is defined as,

g = {(2,4), (4, 2), (5,-1), (8, -9)}

The element of a function is written in the form of order pair where, the first element is input value and second element is the output value.

Since, under the function g the output value of input value 2 is 4,

That is, we can write,

g(2) = 4

Hence, the value of g(4) is 2.
