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
