Practice Algebraic Constraint in Math

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

Quick Recap

A mathematical condition expressed as an equation or inequality that restricts which values the variables are allowed to take.

x^2 + y^2 = 1 constrains (x, y) to lie on a circle โ€” not all points in the plane are allowed.

Example 1

easy
What constraint does x^2 \geq 0 impose on x?

Example 2

medium
What values does \frac{1}{x-3} constrain x to avoid?

Example 3

easy
What constraint does \sqrt{x} impose on x?

Example 4

medium
If x + y = 10 and x, y > 0, what is the maximum of xy?
