Expert Solution

Answer to Problem 4RQ

The statement “ If limx5f(x)=2 and limx5g(x)=0 , then limx5[f(x)/g(x)] does not exist” is true.

Explanation of Solution

Given information:

The given statement is “If limx5f(x)=2 and limx5g(x)=0 , then limx5[f(x)/g(x)] does not exist”.

Calculation:

Let consider limx5f(x)=2 and limx5g(x)=0 . And f and g are two functions of x .

The quotient law of limits is

  limxa(fg)(x)=limxaf(x)limxag(x)

Here, the limxag(x)0

Apply the quotient law of limits on limx5[f(x)/g(x)] .

  limx5[f(x)g(x)]=limxaf(x)limxag(x)

Since, the limxag(x)0 hence limx5[f(x)/g(x)] does not exist.

Therefore, the statement “ If limx5f(x)=2 and limx5g(x)=0 , then limx5[f(x)/g(x)] does not exist” is true.
