Provide an appropriate response.Consider the quartic function f(x) = ax4 + bx3 + cx2 + dx + e, a ? 0. Must this function have at least one critical point? Give reasons for your answer. (Hint: Must  for some x?) How many local extreme values can f have?

What will be an ideal response?


Yes. The derivative is cubic: 4ax3 + 3bx2 + 2cx + d. The derivative approaches -? as x approaches  and it approaches ? as x approaches ?. By the Intermediate Value Theorem,  f'(x) must equal zero at at least one point on the interval -? ? x ? ?.
