inverse of f(x)=20-2x

Solution

inverse

f (x) = 20 - 2 x

Solution

- \frac{x - 20}{2}

Solution steps

y = 20 - 2 x

Replace

x

with

y

x = 20 - 2 y

Solve for

y, x = 20 - 2 y

- \frac{x - 20}{2}

Popular Examples

domain of f(x)=(sqrt(1-x^2))/x domain

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

domain of-2x^3+36x^2 domain

- 2 x^{3} + 36 x^{2}

domain of f(x)= 1/(\sqrt[4]{x^2-7x)}domain

intercepts of f(x)=-4x intercepts

f (x) = - 4 x

perpendicular y=-7x+2 perpendicular

y = - 7 x + 2
