Short answer: No it is NOT positive values of y from 4 to infinity.....
Correct answers 2 4 5 choice Ooops option 5 is not correct....my mistake [ 2,2.5] WOULD be correct.
(2, 2.5) COULD be correct even though it does not include 2 and 2.5 Sorry for the confusion...I will change my answer AGAIN to say YES this answer iis correct.......
It is positive on the interval(s) on x where the function is above the x axis.....note that these are
(-inf, -2) and (0, 4)
Not sure I agree with this Chris......as I stated...it IS true that it is positive for this interval too (2,2,5)
