Question #c54b7

Answer 1

You will get `-15` after evaluation

Explanation:

The function is `f(color(red)x)=-3color(red)x^2+color(red)x-1`

To find the value that will result from inputting this `x` value (`color(red)(-2)`), replace `-2` instead of `x` in the function

`f(color(red)(-2))=-3(color(red)(-2))^2+color(red)(-2)-1`

`f(-2)=color(green)(-3(4))color(blue)(-2-1)`

`f(-2)=color(green)(-12)color(blue)(-3)`

`f(-2)=-15`
