Question
For the following function, find the first derivative, do a sign graph of the
first derivative, and classify the nature of all critical points. Do not graph.
f (x) = 3x4 – 4x³
O C.P.s are x =
O is a r. max., x =
1 is a r. min.
O C.P.s are x = 0, is a stationary point, = 1 is a r. min., x = 12, is a r. max
O C.P.s are x = 0, is a stationary point, = 1 is a r.min.
O C.P.s are x = -1 is a r.min, x = 0 is a vertical tangent
O C.P.s are x = 1 is a r.min, x = 0, is a cusp
