the roots of f(x)=-2x^2+8x+13 are and the vertex of the parabola is at

the vertex of the parabola is at (2,21)

The roots are down below. I didn’t know how to type them out

Explanation:

Roots:

Move the terms aside.

x + 2x^2 - 8x - 13 = 0

Simplify it:

-7x + 2x^2 - 13 = 0

And just use the quadratic formula

“ x = -b + sqrt(b^2 - 4ac)/2a , x = -b— sqrt(b^2 - 4ac)/2a “

and it should end up looking like the picture down below.
