Chapter 2.5, Problem 2E

(a)

To determine

**To fill:** The appropriate direction of the graph for

Expert Solution

The graph of

Let the graph of

Add a constant *c* in

Add a constant to a function shifts its graph horizontally.

If *c* is positive then the graph will shifts upward by *c* unit at all points.

If *c* is negative then the graph will shifts downward by *c* unit at all points.

The given equation is,

Compare equation (1) and (2) and obtain

Since the value of *c* is

Hence, the graph of

Expert Solution

The graph of

Let the graph of

Add a constant *c* in

Add a constant to a function shifts its graph horizontally.

If *c* is positive then the graph will shift to the left by *c* unit at all points.

If *c* is negative then the graph will shift to the right by *c* unit at all points.

The given equation is,

Compare equation (3) and (4) and obtain

Since the value of *c* is

Hence, the graph of
