y = −1/4x^2 + 4x − 19
1. Use x = -b/2a to find x.
x = -4/2(-1/4)
x = -4/(-1/2)
x = -4/1 • (-2/1)
x = 8/1
x = 8
2. Plug x into the function to find your vertex.
Replace every x you see in the function with 8 and do the math.
Take it from here.
Answer:
Step-by-step explanation:
Hello,
we assume that a is different from 0 otherwise there is not much we can say on c and then we can write
a(c+b)=d
<=> ac+ab=d
<=> ac = d - ab
<=> 
Hope this helps
