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

The negative x-intercept is at (

The positive x-intercept is at (

,0).

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

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

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