inverse of f(x)=(2x+5)/7

Solution

inverse

f (x) = \frac{2 x + 5}{7}

Solution

\frac{7 x - 5}{2}

Solution steps

y = \frac{2 x + 5}{7}

Replace

x

with

y

x = \frac{2 y + 5}{7}

Solve for

y, x = \frac{2 y + 5}{7}

\frac{7 x - 5}{2}

Popular Examples

range of f(x)= x/((x-1)(x-2))range

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

extreme y=(x^3)/((x-1)^2)extreme points

y = \frac{x ^{3}}{( x - 1 ) ^{2}}

domain of f(x)=sqrt(9x-8)domain

f (x) = 9 x - 8

monotone 4-(x-2)^2 monotone intervals

4 - (x - 2)^{2}

extreme f(x)=x^3-7x^2+15x+9 extreme points

f (x) = x^{3} - 7 x^{2} + 15 x + 9
