It’s saying the equation is going to be equal to.
HOPE THIS HELPS
Make the question more clear i cant understand it :/ include all the information from the actual question to get the best answer.
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.
<span>x^3=8/125
x^3 = 2^3 / 5^3
x = 2/5
hope it helps</span>
