Question

Find the vertex, the line of symmetry, and the maximum or minimum value of f(x). Graph the function. f(x)=-4(x+1)^2+3
So far I have the vertex: (-1,3), The line of symmetry x=-1, but what is the maximum or minimum value of f(x)??

Answer 1

vertex (-1,3)
axis of symmetry x= -1
maximum or minimum value is the same as the vertex.
For this case it is, it is the maximum value

Answer 2

It's a parabola so the vertex must be either minimum or maximum value

Answer 3

So is it just 3? I attached my problem. I'm not sure how to key in the value.

Answer 4

yea 3

Answer 5

Okay, thank you! :)
