inverse of f(x)=4x-20

Solution

inverse

f (x) = 4 x - 20

Solution

\frac{x + 20}{4}

Solution steps

y = 4 x - 20

Replace

x

with

y

x = 4 y - 20

Solve for

y, x = 4 y - 20

\frac{x + 20}{4}

Popular Examples

asymptotes of y=(4+x^4)/(x^2-x^4)asymptotes

y = \frac{4 + x ^{4}}{x ^{2} - x ^{4}}

extreme y=(x-4)(3x+4)^3 extreme points

y = (x - 4) (3 x + 4)^{3}

asymptotes of f(x)= 1/(x-5)+2 asymptotes

f (x) = \frac{1}{x - 5} + 2

domain of (x+1)/(sqrt(x^2+1))domain

\frac{x + 1}{x ^{2} + 1}

inverse of f(x)= 1/(x-7)inverse

f (x) = \frac{1}{x - 7}
