Sagot :

This is an interesting question. Which intervals are they talking of ? Obviously the x axis, always remember that.

So visually we can assume that h(x) is strictly positive over (-∞, 0)U(3.6, +∞)

the only interval in the list that respect this is -1 < x < 0 so this one is the correct answer.

Good luck
