inverse of f(x)=sqrt(7x+3)-15

inverse

f (x) = 7 x + 3 - 15

\frac{x ^{2} + 30 x + 222}{7}

Solution steps

y = 7 x + 3 - 15

Replace

x

with

y

x = 7 y + 3 - 15

Solve for

y, x = 7 y + 3 - 15

\frac{x ^{2} + 30 x + 222}{7}

f (x) = 3 - 5 x^{3}

y = 2 - \frac{1}{2 x}

- \frac{8}{7} x + 8

\frac{2 x}{5 x - 6}

f (x) = 5 csc (\frac{x + π}{2.1}) - 6.5
