Question

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

Answer 1

Answer:

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

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

Step-by-step explanation:

Answer 2

Answer:

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
