Question

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

Answer 1

negative x intercept is at -1/3

positive x intercept 4

Explanation:

Answer 2

Answer:
`x=-(1)/(3), 4`

Explanation:

Graphs intersect the x-axis where y=0, so we can set f(x)=0.

`3x^2 - 11x-4=0 \\ \\ (3x+1)(x-4)=0 \\ \\ x=-(1)/(3), 4`
