20/20 Function Domains против RationalNumberCalculator Использование & Stats

A power learning aid combines Coaching Calculators and Guides to help students find the domains of simple rational functions and radical functions. The Coaching Calculator covers rational functions such as : f(x) = (3x + 6)/9 f(x) = (x² - 4)/(3x + 6) f(x) = (x² - 9)/(2x² + 4x - 6) and radical functions such as : f(x) = √(2x + 6) f(x) = √((x² - 5x + 6) Domains are given in set-builder and interval notation. The Guide also looks at radical functions such as : f(x) = -2/√(x - 3) f(x) = (2x + 3)/(x - √(x + 2)) It's ideal for students as the menu design reinforces each problem solving step. Examples highlight and simplify algebra that students find hard.
