Question

Does the following equation, y= -x2 -10x +1 have a maximum or
minimum. Explain

Answer 1

Explanation:

Your y= -x2 -10x +1 should be written as y = -x^2 -10x +1. This is a quadratic function. Because the coefficient (-1) of the x^2 term is negative, we know immediately that the graph (a parabola) opens down, and thus has a maximum.
