Question

What is the value of g(1⁄2) when g(x) = 2x2? What is the input? What is the output?

Answer 1

`g((1)/(2)) = 0.5`

The input is
`x = (1)/(2)` and the output is
`g(x) = g((1)/(2)) = 0.5`

Explanation:

Suppose we have a function g(x) = a. The input is the value of x and the output is the value of g.

In this question:

`g(x) = 2x^(2)`

We want g(1/2) = g(0.5). So

`g(0.5) = 2*(0.5)^(2) = 2*0.25 = 0.5`

`g((1)/(2)) = 0.5`

The input is
`x = (1)/(2)` and the output is
`g(x) = g((1)/(2)) = 0.5`
