Answer

Please see the graph.

Work Step by Step

The red graph is $ y>x^{2}$, and the blue graph is $ y\ge2x+1$. $y > x^2$ Since we have a greater than sign, we use a dotted line. We also pick the point $(0,2)$ to determine what side of the line to shade. $y \ge 2x+1$ Since we have a greater than or equal to sign, we use a solid line. We also pick the point $(0,2)$ to determine what side of the line to shade. $(0,2)$ $y > x^2$ $2 > 0^2$ $2 > 0$ (true, so we shade the side of the graph with the point) $(0,2)$ $y \ge 2x+1$ $2 \ge 2*0+1$ $2 \ge 0+1$ $2 \ge 1$ (false, so we shade the side of the graph without the point) The overlap of the two graphs is the solution set.
