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

A.

x-intercepts: (3, 0) and (2, 0)

y-intercept: (0, 6)

B.

x-intercepts: (3, 0) and (-2, 0)

y-intercept: (0, - 6)

C.

x-intercepts: (-3, 0) and (2, 0)

y-intercept: (0, - 6)

D.

x-intercepts: (-3, 0) and (2, 0)

y-intercept: (0, 6)

    The y intercept would be when x=0,

    so, y=0^2+0-6

    this will make y = - 6

    y intercept is at (0,-6)

    As for x intercept, this is quadratic so it will have two intercept where y=0

    y=x^2+x-6

    You'll have to break up the equation to find the answer

    0 = (x+3) (x-2)

    x+3=0 leads to x = - 3

    x-2=0 leads to x = 2

    so the x intercepts are at (2,0) and (-3,0)
