Example Calculations

Example 1:

Function: f(x) = x² − 8x

Result:
Derivative: f'(x) = 2x − 8
Set f'(x) = 0
2x − 8 = 0
x = 4

Critical Point: x = 4

---

Example 2:

Function: f(x) = x³ − 6x² + 9x

Result:
Derivative: f'(x) = 3x² − 12x + 9
Solve: 3x² − 12x + 9 = 0
x = 1, x = 3

Critical Points: x = 1 and x = 3

These examples show how critical points help locate turning points on a graph.
