Let p(x) = x3 -ax, where a is constant
a) If a<0, show that p(x) is always increasing.
substituting in values
b) If a>0, show that p(x) has a local maximum and a local minimum.
c) Sketch and label typical graphs for the cases when a<0 and when a>0.
Find the value(s) of x for which:
a) f(x) has a local maximum or local minimum. Indicate which ones are maxima and which are minima.
b) f(x) has a global maximum or global minimum
f(x) = x10 - 10x, and 0 <= x <=2

Neat, step-by-step solutions using graphs are provided.
