Question

Is the Y value of the vertex of 4x squared plus 8X minus 8. help meee​

Answer 1

Answer:

y = -12

Step-by-step explanation:

You first calculate the x coordinate using the equation x = $\frac{-b}{2a}$, which in this case is $\frac{-8}{8} = -1$.

Then plug that x value into the equation to get the y coordinate:

4(-1)²+8(-1)-8 = -12
