inverse of f(x)=2-9x

Solution

inverse

f (x) = 2 - 9 x

Solution

- \frac{x - 2}{9}

Solution steps

y = 2 - 9 x

Replace

x

with

y

x = 2 - 9 y

Solve for

y, x = 2 - 9 y

- \frac{x - 2}{9}

Popular Examples

domain of f(x)=-6 domain

f (x) = - 6

extreme f(x)=sqrt(x^2+1)extreme points

f (x) = x^{2} + 1

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

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

domain of sqrt(3x-7)domain

3 x - 7

inflection f(x)=-4x^3+12x^2-2 inflection points

f (x) = - 4 x^{3} + 12 x^{2} - 2
