inverse of f(x)=\sqrt[3]{x+7}f(x)=3x+7

inverse

\frac{x - 7}{3}

Solution steps

y = 3 x + 7

Replace

x

with

y

x = 3 y + 7

Solve for

y, x = 3 y + 7

\frac{x - 7}{3}

+ \frac{5}{x ^{2} + 1}

(\frac{x ^{5}}{10})^{\frac{1}{7}}

f (x) = 2972230 x - 15682

x^{2} - 145

f (x) = \frac{2}{( x - 1 ) ^{2}} + 3
