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

Answer 1

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

$\\ \sf\longmapsto g(2)$

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

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

$\\ \sf\longmapsto -8+1$

$\\ \sf\longmapsto -7$

Answer 2

Answer:

$g(2)=-7$

Step-by-step 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

$2 \times 2 = 4$

Solve the parenthesis. Then complete solution.

$g(x)=-2(4)+1\\-2 \times 4 = -8\\-8 + 1 = -7$

$g(2)=-7$
