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

Solution

inverse

f (x) = x^{2} - 4 x

Solution

2 + x + 4, 2 - x + 4

Solution steps

y = x^{2} - 4 x

Replace

x

with

y

x = y^{2} - 4 y

Solve for

y, x = y^{2} - 4 y

2 + x + 4, 2 - x + 4

Popular Examples

range of (x^2-5x-6)/(x+1)range

\frac{x ^{2} - 5 x - 6}{x + 1}

intercepts of y=3x-3 intercepts

y = 3 x - 3

asymptotes of f(x)=(5x-15)/(3x-15)asymptotes

f (x) = \frac{5 x - 15}{3 x - 15}

extreme y=x^2-2x-1 extreme points

y = x^{2} - 2 x - 1

inverse of f(x)=(2x-1)/(3-x)inverse

f (x) = \frac{2 x - 1}{3 - x}
