Question

The graph is shown is correctly represented by

Options

A) y = x2 - x - 2

B) y = x2 - 3x + 2

C) y = x2 - x - 1

D) y = x2 + x - 2

The correct answer is A.

Explanation:

The graph crosses the x-axis at x = -1 and x = 2

Thus, x + 1 = 0 and x - 2 = 0

x2 - 2x + x - 2 = 0

x2 - x - 2 = 0

giving y = x2 - x - 2
