Letter a$.$ Determine a small number of quadratic Bezier curves that interpolate a subset of these points and give a much better looking rendering of the lower case letter a than the piecewise linear interpolants shown. Determine suitable

control points

for the quadratic Bezier curves $($ experimentation$).$
