inverse of f(x)=7-9x

Solution

inverse

f (x) = 7 - 9 x

Solution

- \frac{x - 7}{9}

Solution steps

y = 7 - 9 x

Replace

x

with

y

x = 7 - 9 y

Solve for

y, x = 7 - 9 y

- \frac{x - 7}{9}

Popular Examples

domain of f(x)=(x^2+5x+6)/(x^2-3x-10)domain

f (x) = \frac{x ^{2} + 5 x + 6}{x ^{2} - 3 x - 10}

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

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

perpendicular y=2x+3,(1,5)perpendicular

y = 2 x + 3, (1, 5)

domain of f(x)=(2x)/(x^2-4)domain

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

range of (3x)/(7x-1)range

\frac{3 x}{7 x - 1}
