Solution

inverse

f (x) = 2 x + 1

Solution

\frac{x - 1}{2}

Solution steps

y = 2 x + 1

Replace

x

with

y

x = 2 y + 1

Solve for

y, x = 2 y + 1

\frac{x - 1}{2}

Popular Examples

domain of (x+1)/(x-5)domain

\frac{x + 1}{x - 5}

domain of f(x)=7x-4 domain

f (x) = 7 x - 4

domain of f(x)= 1/(x-8)domain

f (x) = \frac{1}{x - 8}
