Recap: Radical Functions

Part of the Radicals & Rational Exponents section of Coddy's Algebra 2 journey. Lesson 35 of 40.

Challenge

Use $g\left(x\right) = cbrt\left(4x-19\right)$ to work out $g\left(-2\right)$ . Tap the move that uses the rule, then type each next line.

Try it yourself

g\left(-2\right)

Simplify

Given $g\left(x\right) = \sqrt[3]{4x-19}$
