inverse of f(x)=(4x)/(x-7)

Solution

inverse

f (x) = \frac{4 x}{x - 7}

Solution

\frac{7 x}{x - 4}

Solution steps

y = \frac{4 x}{x - 7}

Replace

x

with

y

x = \frac{4 y}{y - 7}

Solve for

y, x = \frac{4 y}{y - 7}

\frac{7 x}{x - 4}

Popular Examples

symmetry 3x^2+7x+5v(H,K)symmetry

3 x^{2} + 7 x + 5 v (H, K)

asymptotes of y=(3x^2-3x)/(x^2+x-12)asymptotes

y = \frac{3 x ^{2} - 3 x}{x ^{2} + x - 12}

distance (-10,-7),(2,-16)distance

(- 10, - 7), (2, - 16)

parity f(x)=x+1+1/x parity

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

domain of f(x)=sqrt(16-x^2)+sqrt(x+3)domain

f (x) = 16 - x^{2} + x + 3
