Question 217214: 1)A function f is given. x^4-9x^2
(a) Use a graphing device to draw the graph of f.
(b) State approximately the intervals on which f is increasing and on which f is decreasing. Use (0, 0) for any remaining intervals that you do not need. (Round your answers to the nearest tenth.)
Increasing.
It asks for (?,?) Left most increasing
(?,?) right most increasing
(?,?) left most decreasing
(?,?) right most decreasing

Looks like a tooth.
