Chapter 3: Q. 9 (page 260)

Sketch the graph of a function f with the following properties:

f is continuous and defined on R;

f(0) = 5;

f(鈭�2) = 鈭�3 and f '(鈭�2) = 0;

f '(1) does not exist;

f' is positive only on (鈭�2, 1).

Graph is:

Step by step solution

01

Step 1. Given information

We have been given the following properties of a function f:

f is continuous and defined on R;

f(0) = 5;

f(鈭�2) = 鈭�3 and f '(鈭�2) = 0;

f '(1) does not exist;

f' is positive only on (鈭�2, 1)

We have to sketch the graph of this function.

02

Step 2. Sketch the graph

Since, f鈥�(鈭�2)=0so -2is a critical point.

and f'(1)oes not exist so it has extremum at 1.

also f'is positive only on (-2,1) so f is increasing in the interval (-2,1)

Thus, the Graph is:
