20/20 Function Domains vs Lafourche Parish Sheriff Usage & 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.
