What is the vertex of the function

Mathematics
1 answer:
Kipish [7]4 years ago
8 0

Answer:

(4, -25)

Step-by-step explanation:

In this case, the quadratic formula is in the form:

ax² + bx + c

Since they also give you the formula for the vertex, you just need to plug the values in.

The x coordinate in the vertex is 8/2(1), or 4.

You take the x = 4 and plug it into your quadratic equation.

f(4) = 16 - 32 -9

= -25

The vertex is (4, f(4)) or (4, -25)

I hope this helps!
