Question

Find the values of y = r(x) = ∛x for

Answer 1

$\bf y=r(x)=\sqrt[3]{x}\quad x= \begin{cases} -2.197\\ -1.331\\ 0\\ 1.331\\ 2.197\\ 3.375\\ 4.913 \end{cases}\implies y= \begin{cases} \sqrt[3]{-2.197}\\ \sqrt[3]{-1.331}\\ \sqrt[3]{0}\\ \sqrt[3]{1.331}\\ \sqrt[3]{2.197}\\ \sqrt[3]{3.375}\\ \sqrt[3]{4.913} \end{cases}$

so.. .get the pair and plot them then, all you need is your calculator to get the cubic root of the provided value.
