## Definition, Graph, How to Find Critical Points?

We say that x = c x = c is a critical point of the function f (x) f ( x) if f (c) f ( c) exists and if either of the following are true. f ′(c) =0 OR f ′(c) doesn't exist f ′ ( c) = 0 OR f ′ ( c) doesn't

## 3.1 Critical Numbers

Since we can’t factor the quadratic expression, we can use the quadratic formula to determine the critical numbers of f ( x) instead. x = − ( − 8) ± ( − 8) 2 – 4 ( 3) ( 1) 2 ( 3) = 8 ± 64 – 12 6 = 8 ± 52
