Its easy 
just substitute (-3) in the place of 'a'.

f(-3) = -2(-3)^2 - 5(-3) +4
        = -18 + 15 + 4
        = 1

I hope this helped :D

F(-3) = -2(-3)2 - 5(-3) +4
            - 6 x 2 -15 + 4
                - 12 -15 +4
                    - 27 + 4
                           -23

I believe this is how to solve the equation. I could be wrong.

Answer:

y= -2/3x+490

slope: -2/3

y-intercept: 490

Step-by-step explanation:

Y-intercept form is y=mx+b, so you would first subtract 2x from both sides to get 3y= -2x+1,470. Then you divide both sides by 3, to get y= -2/3x+490. -2/3 is in the place of m, so it is the slope, and 490 is in the place of b, so it is the y-int.
