#### To determine

**To sketch: **Graph of derivative

#### Answer

Graph of derivative is along with original graph

#### Explanation

**1) Given:**

**2) Concept:**

When original graph is increasing, its derivative is positive.

When original graph is decreasing, its derivative is negative.

The maxima and minima of f(x), gives zeros of f â(x) because at these points the curve has horizontal tangent. The slope of a horizontal line is zero.

**3) Calculation:**

When original graph is increasing, its derivative is plotted as positive.

When original graph is decreasing, its derivative is plotted as negative.

The maxima and minima of f(x), gives zeros of fâ(x).

Thus the graph of derivative along with its derivative is:

**Conclusion:**

Therefore, the required derivative along with its original graph is
