3.3. The First Derivative Test http://www.ck12.org
For problems #7–10:
a. Use the First Derivative Test to find the intervals where the function increases and/or decreases b. Identify all
max, mins, or relative max and mins c. Sketch the graph
- f(x) =−x^2 − 4 x− 1
- f(x) =x^3 + 3 x^2 − 9 x+ 1
- f(x) =x^23 (x− 5 )
- f(x) = 2 x
√
x^2 + 1
