Let
f(x) = x3 − 2x2.
Find the point(s) on the graph of f where the tangent
line is horizontal.
(x, y)
=
0
(smaller x-value)
(x, y)
=
(larger x-value)
B)
A straight line perpendicular to and passing through the point
of tangency of the tangent line is called the normal to
the curve. Find an equation of the tangent line and the normal to
the curve y = x3 - 3x + 1 at
the point (3, 19)....
