inverse of f(x)=(x+8)/(x-7)

Solution

inverse

f (x) = \frac{x + 8}{x - 7}

Solution

\frac{8 + 7 x}{x - 1}

Solution steps

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

Replace

x

with

y

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

Solve for

y, x = \frac{y + 8}{y - 7}

\frac{8 + 7 x}{x - 1}

f (x) = 2 x^{3} - 3 x^{2} - 12 x + 7

domain of f(x)=x^2+3x+1 domain

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

inverse of f(x)=(3)^{x+2}+1 inverse

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