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#
