Question

What is the absolute maximum for the function f(x)=-6x^2+8x-5?

Answer 1

that would be the vertex... do you know how to locate the vertex of the parabola?

Answer 2

With the quadratic formula?

Answer 3

rewrite the equation so you can find the vertex

Answer 4

this way

Answer 5

you can do that ^^^ as @gvt016 stated...
but an easier way is to use the fact that \(\large x=\frac{-b}{2a} \) will give you the x-coordinated of the vertex....

Answer 6

*coordinate

Answer 7

yes that is the shorter way, you must make a choice
