Chapter 2, Problem 6RQ
To determine

To find: Whether the statement “ If limx6[f(x)g(x)] exists, then the limit must be f(6)g(6) ” is true or true.

Expert Solution

Answer to Problem 6RQ

The statement “If limx6[f(x)g(x)] exists, then the limit must be f(6)g(6) ” is true.

Explanation of Solution

Given information:

The given statement is “If limx6[f(x)g(x)] exists, then the limit must be f(6)g(6) ”.

Calculation:

Let consider that limx6[f(x)g(x)] is exists.

Consider f and g are two functions of x .

The product law of the limits is

  limxa(fg)(x)=limxaf(x)limxag(x)

The expression is

  limx6[f(x)g(x)]

Apply the product law of the limits.

  limx6[f(x)g(x)]=limx6f(x)limx6g(x)=f(6)g(6)

Therefore, the statement “If limx6[f(x)g(x)] exists, then the limit must be f(6)g(6) ” is true.
