inverse of f(x)=9-2x

Solution

inverse

f (x) = 9 - 2 x

Solution

- \frac{x - 9}{2}

Solution steps

y = 9 - 2 x

Replace

x

with

y

x = 9 - 2 y

Solve for

y, x = 9 - 2 y

- \frac{x - 9}{2}

Popular Examples

slope ofintercept y+4=-1/4 (x+1)slope intercept

y + 4 = - \frac{1}{4} (x + 1)

critical f(x)=xln(x)critical points

f (x) = x ln (x)

slope of f(x)= 2/5 x-5 slope

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

inverse of f(x)=x+sqrt(x)inverse

f (x) = x + x

intercepts of f(x)=2x^2+7x-4 intercepts

f (x) = 2 x^{2} + 7 x - 4
