#### 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 ’(x)

When original graph is of straight line, its derivative is constant same as its slope

At corners, derivative does not exist.

**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 points on f(x) with horizontal tangents, gives zeros of f ’(x)..

When original graph is of straight line, its derivative is constant (same as the slope of line)

So the last part is drawn as constant.

At corners derivative is not exist. So the graph of derivative breaks into two parts at this pont.

Thus graph of derivative along with its derivative is:

**Conclusion:**

Therefore, the required derivative along with its original graph is
