This equation is in vertex form. Vertex form is y=a(x-h)^2+k, where (h,k) is the vertex. In this equation, h= -3, and k= -4. So, the vertex would be at (-3,-4). A tells us if the parabola will be positive or negative. In this case, it is positive, so the parabola opens upward. Then, you can solve for x-intercept by letting y=0 and solving for x. Then, you can find the y-intercept by setting x=0 and solving for y. Finally, graph the parabola.
 
        
        
        
Answer:
 y($) =  405- 20x
Step-by-step explanation:
Number of short driveways = x
Number of long driveways = 9-x
Fee per long driveway = $45
Fee per short driveway= $25
Total amount = y
y ($) =  25x + 45 (9-x)
       =  25x  + 405 -45x
       = 405- 20x
