Question

What are the x– and y–intercepts of the graph of y = x2 + x – 6?

x–intercepts: (3, 0) and (2, 0)
y–intercept: (0, 6)

x–intercepts: (3, 0) and (–2, 0)
y–intercept: (0, –6)

x–intercepts: (–3, 0) and (2, 0)
y–intercept: (0, –6)

x–intercepts: (–3, 0) and (2, 0)
y–intercept: (0, 6)

Answer 1

The x-intercepts are the roots, and the y-intercept is where x=0. Simply solve!

Answer 2

First, the y-intercept. Plug in x=0 and you get 0+0-6, or -6.

Answer 3

Next the x-intercepts. Factoring, we have y=(x+3)(x-2). So x=-3,2. So the x-intercepts are (-3,0) and (2,0), while the y-intercept is (0,-6). So it's the third choice.

Answer 4

Makes sense?
