(a)

To determine

To find: The value of limxf(x).

Expert Solution

Answer to Problem 3E

The value of limxf(x)=2.

Explanation of Solution

From the given graph, it is observed that the curve approaches 2 as x approaches infinity from either side.

(b)

To determine

To find: The value of limxf(x).

Expert Solution

Answer to Problem 3E

The value of limxf(x)=2.

Explanation of Solution

From the given graph, it is observed that the curve approaches 2 as x approaches negative infinity from either side.

(c)

To determine

To find: The value of limx1f(x).

Expert Solution

Answer to Problem 3E

The value of limx1f(x)=.

Explanation of Solution

From the given graph, it is observed that the curve approaches infinity as x approaches 1 from either side.

(d)

To determine

To find: The value of limx3f(x).

Expert Solution

Answer to Problem 3E

The value of limx3f(x)=.

Explanation of Solution

From the given graph, it is observed that the curve approaches as x approaches 3 from either side.

(e)

To determine

To find: The equations of the asymptotes.

Expert Solution

Answer to Problem 3E

Solution: The equations of the asymptote are x=1,x=3,y=2 and y=2.

Explanation of Solution

Recall the definition that the line x=a is said to be a vertical asymptote of the function f(x), if either limxaf(x)=± or limxa+f(x)=±.

Recall the definition that the line x=a is said to be a horizontal asymptote of the function f(x), if either limx±f(x)=a or limx±f(x)=a.

From the limits obtained from the parts (a)-(d), it can be concluded that the equations of asymptote are x=1,x=3,y=2 and y=2.
