I thought I did the problem correct but the teacher’s feedback has me stumped can someone please explain to me what she is talking about and what I did wrong?
The problem I did:
3 x/ 3 ≥4/3
out, because (3x-4)2 ≥ 0 does
NOT imply that (3x - 4) ≥ 0. Also you are missing division symbols. 43 is
not the same as 4/3.
working with a polynomial inequality, first solve the related equation to get
critical values. In this case, the equation (3x-4)2= 0
has the solution x = 4/3.
The value 4/3 splits up the x-axis into the intervals (- ∞ ,
4/3) and (4/3, ∞).
