You have positive times a positive divided by a positive. You're going to be concave upwards because your second derivative is going to be greater than 0. Concave upwards. Finally, when x is just less than negative 3, remember when I write this, I don't mean for all x's larger than negative 3 or all x's smaller than negative 3. There's actually no notation that would say just as we just approach 3, in this case, from the left. What happens if we just go to minus 3.11 or 3.01? This term right here is going to be positive.
