Below

Explanation:

First of all, you know that the graph is a parabola because it is x^2. The 2 at the front means that the graph is narrower than the normal x^2 by around twice as much. The 4 means that you have to shift the parabola up by 4 units.

graph{x^2 [-10, 10, -5, 5]} this is your x^2

graph{2x^2 [-10, 10, -5, 5]} this is your 2x^2

graph{2x^2+4 [-10, 10, -5, 5]} this is your 2x^2+4
