F(x)=x²+4x-7 determine the vertex

The vertex of this parabola is

Step-by-step explanation:

One way of finding the x-coordinate of the vertex of a parabola is by using the equation

From the function , we can see that

This means that

So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.

Thus, the vertex of this parabola is

the answer is 62

9 x 8 divided by (5-3)=36
