Without a calculator, sketch the following function. Make sure to label both the x and y intercepts. (HINT: Find the zeroes and y-intercept in terms of c)
Function: y=x^2-4cx+4c^2, for c > 0
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.
This is the point when the x-value is zero:
Thus, the y-intercept ...
This solution explains how to graph a given function manually.
