Answer:
The negative x-intercept is at (-1/3 , 0).
The positive x-intercept is at (4 , 0).
Step-by-step 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
