Answer:
The value of g(4) is 2.
Step-by-step 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.
