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.

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)
