Answer

Please see the graph.

Work Step by Step

Orange graph: $ y\gt x^2$ Blue graph: $ y\ge2x+1$ $y\gt x^2$ This is a parabola with a vertex at the origin. We pick the point $(2,2)$ to determine what side of the graph to shade. $y\gt x^2$ $2\gt 2^2$ $2\gt 4$ (false) We shade the side of the graph without the point. $y\ge 2x+1$ This is a line with slope of 2 and y-intercept 1. We pick the point $(2,2)$ to determine what side of the graph to shade. $y\ge 2x+1$ $2 \ge 2*2+1$ $2\ge 4+1$ $2 \ge 5$ (false) We shade the side of the graph without the point. The intersection of the two graphs is the solution set of the system of inequalities.
