Question

Find the sum of the x values for which g(x) =-2 if you can explain it to that would be great

Answer 1

As shown in the figure

We need to find the value of x when g(x) = -2

so,

By drawing a parallel line to the x - axis and passing through the point ( 0 , -2) and finding the intersection with the function g(x)

See the following image:

so, g(x) = -2 when

`x=-2,3,4`

the sum of the x - values :

`-2+3+4=5`
