inverse of f(x)=sqrt(x)-9

Solution

inverse

f (x) = x - 9

Solution

x^{2} + 18 x + 81

Solution steps

y = x - 9

Replace

x

with

y

x = y - 9

Solve for

y, x = y - 9

x^{2} + 18 x + 81

Popular Examples

intercepts of f(x)=2x-3y=-3 intercepts

f (x) = 2 x - 3 y = - 3

periodicity of f(x)=4cos(4/3 x)periodicity

f (x) = 4 cos (\frac{4}{3} x)

asymptotes of (4x-20)/(x^2-2x-15)asymptotes

\frac{4 x - 20}{x ^{2} - 2 x - 15}

line (2.25,0.65),(3,1)line

(2.25, 0.65), (3, 1)

domain of f(x)=3x+3 domain
