inverse of f(x)=sqrt(2x-4)

Solution

inverse

f (x) = 2 x - 4

Solution

\frac{x ^{2} + 4}{2}

Solution steps

y = 2 x - 4

Replace

x

with

y

x = 2 y - 4

Solve for

y, x = 2 y - 4

\frac{x ^{2} + 4}{2}

Popular Examples

intercepts of y=3x-1 intercepts

y = 3 x - 1

domain of f(x)=81x^2-90x+25 domain

f (x) = 81 x^{2} - 90 x + 25

domain of (65)/((1-8x)^2)domain

\frac{65}{( 1 - 8 x ) ^{2}}

monotone xe^{1/x}monotone intervals

x e^{\frac{1}{x}}

domain of (4x^2+4x+1)/(2x^3+8x^2)domain

\frac{4 x ^{2} + 4 x + 1}{2 x ^{3} + 8 x ^{2}}
