+x+=+3+ is a vertical line through (3,0 )
+f%28x%29+=+x%5E2+-+3+
+f%283%29+=+3%5E2+-+3+
+f%283%29+=+9+-+3+
+f%283%29+=+6+
( 3,f(3) ) = ( 3,6 )

Here is the plot of the parabola.
I don't know how to plot the vertical line through ( 3,0 )

graph f%28x%29=x%5E2-3
then draw the line x=3 and label the point P=(3,f%283%29)
find f%283%29
f%283%29=3%5E2-3
f%283%29=9-3
f%283%29=6
