Answer 1

The roots of the quadratic function are x = -2 and x = -4. The vertex is at (3, f(3)).

Step-by-step explanation:

The given quadratic function is -x^2-6x-8.

To find the roots of the quadratic function, we can set it equal to zero and solve for x.

-x^2-6x-8 = 0

Factoring the quadratic equation gives us (x+2)(x+4) = 0.

Setting each factor equal to zero, we find that the roots are x = -2 and x = -4.

To find the vertex, we can use the formula x = -b/2a. In this case, a = -1 and b = -6.

Substituting the values of a and b into the formula gives us x = -(-6)/2(-1) = 3. So the vertex is at (3, f(3)).
