    The negative x-intercept is at (-1/3, 0).

    The positive x-intercept is at (4, 0).

    Explanation:

    Where does f (x) = 3x2 - 11x - 4 intersect the x-axis?

    The negative x-intercept is at (-1/3, 0).

    The positive x-intercept is at (4, 0).

    Set f (x) equal to zero so

    3x2 - 11x - 4 = 0

    Plug in a. b, and c into the quadratic formula

    and get 2 solutions:

    1/3 and - 4

    take the opposite signs and put it in the x intercepts
