inverse of f(x)=(x-1)/2

Solution

inverse

f (x) = \frac{x - 1}{2}

Solution

2 x + 1

Solution steps

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

Replace

x

with

y

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

Solve for

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

2 x + 1

Popular Examples

periodicity of f(x)=3sin(1/4 x)periodicity

f (x) = 3 sin (\frac{1}{4} x)

domain of (x^2+3x)/(5x^2-1)domain

\frac{x ^{2} + 3 x}{5 x ^{2} - 1}

domain of f(x)=(sqrt(2x-5))/(3x-9)domain

f (x) = \frac{2 x - 5}{3 x - 9}

perpendicular y=-3/5 x+7 perpendicular

y = - \frac{3}{5} x + 7

intercepts of y=x^3-x intercepts

y = x^{3} - x
