Practice Constraints (Meta) in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

Conditions or restrictions that bound the set of allowable values or solutions in a problem.

The rules of the game. What must be true? What can't happen?

Example 1

easy
Solve \frac{1}{x-2} = 3 and identify all constraints on x before solving.

Example 2

medium
An integer n satisfies two constraints: n > 0 and n < 10, and also n is prime. List all valid values of n.

Example 3

easy
State the domain constraint for f(x) = \sqrt{x - 4} and solve for x when f(x) = 3.

Example 4

medium
A rectangle has area 36 cmยฒ and integer side lengths. List all constraints and find all valid dimension pairs (l, w) with l \ge w.
