Find inverse of f(x)=x^3-9<br>Not sure of my answer!​
Katyanochek1 [597]

as you may already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

\bf \stackrel{f(x)}{y}=x^3-9\implies \stackrel{\textit{quick switcheroo}}{\underline{x}=\underline{y}^3-9}\implies x+9=y^3\implies \sqrt[3]{x+9}=\stackrel{f^{-1}(x)}{y}

Answer: 0.72/20; 1.98/20; 17.3/20

0.036 * 10/10 = 0.36/10 * 2/2 = 0.72/20

0.099 * 10/10 = 0.99/10 * 2/2 = 1.98/20

0.865 * 10/10 = 8.65/10 * 2/2 = 17.3/20
