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.

innocence can be defined as the lack of sin, relating it with the lack of guilt, also it can be a synonime of naivety. most people agree that sins are made out of experiences, intentionally or not, as well as you stop being naive once certain things happen to you throughout your life. so, with this explained, the chosen answers are:
