question 13 (1 point)
which of the following techniques should not be used to evaluate limits?
computing inverses
rationalizing
divide by highest degree
direct substitution

Explanation:

Analyze the question

The question asks to identify which of the listed mathematical techniques is not used to evaluate limits.

Evaluate "Direct substitution"

Using the Direct Substitution knowledge point
Direct substitution is the primary method used to evaluate limits of continuous functions.

Evaluate "Rationalizing" and "Divide by highest degree"

Using the Limit Evaluation knowledge point
Rationalizing is used to resolve indeterminate forms like \(\frac{0}{0}\) involving radicals. Dividing by the highest degree is used to evaluate limits at infinity for rational functions.

Evaluate "Computing inverses"

Computing the inverse of a function is a technique used to find a function's reverse mapping, not to evaluate limits.

Determine the correct option

Since computing inverses is not a limit evaluation technique, it is the correct answer to this "not" question.

Answer:

• (A) Computing inverses (Correct answer)
• (B) Rationalizing
• (C) Divide by highest degree
• (D) Direct substitution
