inverse of f(x)=7-2x

Solution

inverse

f (x) = 7 - 2 x

Solution

- \frac{x - 7}{2}

Solution steps

y = 7 - 2 x

Replace

x

with

y

x = 7 - 2 y

Solve for

y, x = 7 - 2 y

- \frac{x - 7}{2}

Popular Examples

domain of f(x)=(x-3)domain

f (x) = (x - 3)

domain of 1/(x^2+5x-24)domain

\frac{1}{x ^{2} + 5 x - 24}

slope ofintercept y= 2/3 x+5 slope intercept

y = \frac{2}{3} x + 5

domain of f(x)=(sqrt(5-x))/(sqrt(x^2-1))domain

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

slope ofintercept y=-2x-4 slope intercept

y = - 2 x - 4
