Question

[50 point question answer soon! am big confusion]Given g(x )= −2x^2 +1, find the indicated values.

g(2)

Answer 1

`g(2)=-7`

Explanation:

We are given
`g(x)= -2x^2 +1`. And our input value is
`g(2)`. Therefore, replace "x" with 2 for every x you see, then solve:

`g(x)= -2x^2 +1\\\\g(x)=-2(2)^2+1`

2 squared

`2 * 2 = 4`

Solve the parenthesis. Then complete solution.

`g(x)=-2(4)+1\\-2 * 4 = -8\\-8 + 1 = -7`

`g(2)=-7`

Answer 2

`\\ \sf\longmapsto g(x)=-2x^2+1`

`\\ \sf\longmapsto g(2)`

`\\ \sf\longmapsto -2(2)^2+1`

`\\ \sf\longmapsto -2(4)+1`

`\\ \sf\longmapsto -8+1`

`\\ \sf\longmapsto -7`
