inverse of f(x)=9-4x

Solution

inverse

f (x) = 9 - 4 x

Solution

- \frac{x - 9}{4}

Solution steps

y = 9 - 4 x

Replace

x

with

y

x = 9 - 4 y

Solve for

y, x = 9 - 4 y

- \frac{x - 9}{4}

Popular Examples

domain of f(x)=sqrt(5)cos(1.2x)domain

f (x) = 5 cos (1.2 x)

periodicity of y=5sin(2x-pi/3)+1 periodicity

y = 5 sin (2 x - \frac{π}{3}) + 1

asymptotes of f(x)=(3x)/(x+2)asymptotes

f (x) = \frac{3 x}{x + 2}

asymptotes of f(x)=(x+3)/(x(x+1))asymptotes

f (x) = \frac{x + 3}{x ( x + 1 )}

asymptotes of f(x)=(x^3-x)/(x^2-6x+5)asymptotes

f (x) = \frac{x ^{3} - x}{x ^{2} - 6 x + 5}
