inverse of f(x)=9+sqrt(4+x)

Solution

inverse

f (x) = 9 + 4 + x

Solution

x^{2} - 18 x + 77

Solution steps

y = 9 + 4 + x

Replace

x

with

y

x = 9 + 4 + y

Solve for

y, x = 9 + 4 + y

x^{2} - 18 x + 77

Popular Examples

domain of f(x)=3-2x-x^2 domain

f (x) = 3 - 2 x - x^{2}

slope of-1/2 (-3)y=-3 slope

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

domain of f(x)=-x^2 domain

f (x) = - x^{2}

extreme f(x)=-32x+36x^{1/2}+24 extreme points

f (x) = - 32 x + 36 x^{\frac{1}{2}} + 24

domain of f(x)=(x-3)/(2x^2-3x-20)domain

f (x) = \frac{x - 3}{2 x ^{2} - 3 x - 20}
