inverse of f(x)= 2/5 x+4

Solution

inverse

f (x) = \frac{2}{5} x + 4

Solution

\frac{5 x - 20}{2}

Solution steps

y = \frac{2}{5} x + 4

Replace

x

with

y

x = \frac{2}{5} y + 4

Solve for

y, x = \frac{2}{5} y + 4

\frac{5 x - 20}{2}

Popular Examples

inverse of f(x)=3x^3-12 inverse

f (x) = 3 x^{3} - 12

inverse of f(x)=-3-2x inverse

f (x) = - 3 - 2 x

inverse of f(1)=-3x+3+sqrt(18x-18)inverse

f (1) = - 3 x + 3 + 18 x - 18

range of f(x)=(x+2)/(x-3)range

f (x) = \frac{x + 2}{x - 3}

domain of f(x)=10+3/(2x-1)domain

f (x) = 10 + \frac{3}{2 x - 1}
