The graph that has the equation y = -x² + 2x is in option D

How to find the graph

We can find the graph by rewriting the equation in vertex form

y = -x² + 2x

Complete the square inside the parentheses:

y = -(x² - 2x + 1 - 1)

y = -(x - 1)² + 1

the vertex of the quadratic function is at (1, 1), this match with graph in option d
