- Curve Sketching Course Packet on critical points Consider the function /(x) = (5x2 - 9)2/3. Enter the number of critical pointsumbers of A(x). Determine the x-coordinates of the critical points. Enter your answer as a comma-separated list of values. The order of the values does not matter. Enter DNE if f(x) does not have any critical points. 14.
