inverse of f(x)=((1+2x))/(x+7)

inverse

f (x) = \frac{( 1 + 2 x )}{x + 7}

\frac{1 - 7 x}{x - 2}

Solution steps

y = \frac{1 + 2 x}{x + 7}

Replace

x

with

y

x = \frac{1 + 2 y}{y + 7}

Solve for

y, x = \frac{1 + 2 y}{y + 7}

\frac{1 - 7 x}{x - 2}

18500 (0.04 - r^{2})

f (x) = - 6 x^{2} - 24 x - 31

f (- 1) = \frac{x + 3}{x + 9}

f (x) = 5^{x} + 6

f (x) = 16 ln (tan (x))
