I won't be able to graph for you because I am currently on phone but I will tell how to graph an Inequality in coordinate plane.
We don't need to solve the Inequality. The graph will do.
We draw the parabola with the vertex at (0,4) Basically plot point (0,4) then draw parabola.
Because it is < sign, thus the shade/region will be below the graph.
So the shade will be outside of the curve and not inside.
