inverse of f(x)=(x-7)/(x+4)

Solution

inverse

f (x) = \frac{x - 7}{x + 4}

Solution

\frac{- 7 - 4 x}{x - 1}

Solution steps

y = \frac{x - 7}{x + 4}

Replace

x

with

y

x = \frac{y - 7}{y + 4}

Solve for

y, x = \frac{y - 7}{y + 4}

\frac{- 7 - 4 x}{x - 1}

Popular Examples

domain of f(x)= 1/(sqrt(x-9))domain

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

range of-6cos(5x)range

- 6 cos (5 x)

domain of 6x^2+8x-1 domain

6 x^{2} + 8 x - 1

range of f(x)=(10x-1)/(3-5x)range

f (x) = \frac{10 x - 1}{3 - 5 x}

intercepts of f(x)=y^2-2 intercepts

f (x) = y^{2} - 2
