y=x^2-4cx+4c^2, for c > 0
When plotting a parabola, the most important points are the x and y intercepts. These are the points where the parabola crosses the x and y axes.
y-intercept:
This is the point when the x-value is zero:
x=0
Thus,
y=x^2-4cx+4c^2=(0)^2-4c*(0)+4c^2=4c^2
Thus, the y-intercept ...
