I am trying to find the x-intercepts of this function.

Okay, so I make the domain

x ints, y=0

Basic angle

is positive in 1st + 2nd quadrants.

(repeated) , (repeated) , (repeated)

Dividing through by 3

(repeated) , (repeated) , (repeated)

So these are the intercepts from

My question is, how do I get the intercepts from ?
