Below are sample questions representative of the exercises included on this worksheet and related ALG2.45 Verifying Equivalent Expressions skill assessments:

Problem 1Difficulty: Mastery

Suppose a student simplifies E1 - E2 and gets 0 for every x in the stated domain. What can the student conclude?

AE1 and E2 are equivalent on that stated domain.

BE1 and E2 are equivalent only at x = 0.

CThe result is not useful because subtraction hides differences.

DThe student still needs at least ten table values before deciding.

Solution & Explanation:If the difference is 0 for every allowed input, then the two expressions have the same value throughout the stated domain.

Problem 2Difficulty: Mastery

What is the best plan for verifying whether sqrt((2x - 6)²) and 2x - 6 are equivalent?

AAssume they are equivalent because squaring and square rooting always cancel.

BRewrite the square root as abs(2x - 6) and identify the domain x >= 3 where it matches 2x - 6.

CTest x = 3 only because one value is enough.

DExpand (2x - 6)² and compare coefficients only.

Solution & Explanation:The square root gives abs(2x - 6), so the sign of 2x - 6 determines the domain where equivalence holds.

Problem 3Difficulty: Mastery

How should you compare x/sqrt(x²) and 1 over all nonzero real numbers?

AThey are equivalent because x and sqrt(x²) always cancel.

BThey are equivalent only when x > 0, so they are not equivalent over all nonzero reals.

CThey are not equivalent because 1 is undefined when x < 0.

DThey are equivalent only when x < 0.

Solution & Explanation:When x < 0, sqrt(x²) = abs(x) = -x, so x/sqrt(x²) = -1 rather than 1.
