Question 313239: f(x)= -x^2+4x-3
f(-3)
Can you help me with this problem? this is what i've done.
f(-3)= -3^2 + 4x -3
-9+4x-3
-3 -3= -7 + 4x -3. Im stuck can you tell me what i need to do to solve this problem.

You can put this solution on YOUR website!
-9+4x-3
-3 -3= -7 + 4x -3
WHY DON'T YOU REPLACE THE 4X TERM WITH (4*-3)?
WHERE DO YOU GET THE -7 TERM?
-----------------------
f(x)= -x^2+4x-3
f(-3)
F(-3)=-(-3)^2+4*-3-3
F(-3)=-9-12-3
F(-3)=-24
