inverse of f(x)=100-2x

Solution

inverse

f (x) = 100 - 2 x

Solution

- \frac{x - 100}{2}

Solution steps

y = 100 - 2 x

Replace

x

with

y

x = 100 - 2 y

Solve for

y, x = 100 - 2 y

- \frac{x - 100}{2}

Popular Examples

\frac{2 - x ^{2}}{1 + x ^{4}}

range of (5x)/(x^2-3x-4)range

\frac{5 x}{x ^{2} - 3 x - 4}

critical f(x)=x^3-9x^2+15x-6 critical points

f (x) = x^{3} - 9 x^{2} + 15 x - 6

intercepts of (9-3x)/(x-4)intercepts

\frac{9 - 3 x}{x - 4}

symmetry x^2+9y^2=9 symmetry

x^{2} + 9 y^{2} = 9
