Question

Find the vertex of the graph of the quadratic function and determine whether it's an absolute maximum or an absolute minimum: y=-2x- 8x - 16.

A. Vertex: (-2,-8); minimum
B. Vertex: (-8,-2); maximum
C. Vertex: (-8,-2); minimum
D. Vertex: (-2,-8); maximum​

Answer 1

A

Explanation:

Because the leading coefficient of this function is negative, we can rule out answers with the vertex as the minimum. using -b/2a, we get -2 which leaves us with A as our answer.
