inverse of f(x)=sqrt(2x+5)

Solution

inverse

f (x) = 2 x + 5

Solution

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

Solution steps

y = 2 x + 5

Replace

x

with

y

x = 2 y + 5

Solve for

y, x = 2 y + 5

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

Popular Examples

asymptotes of y=(2)^x-3 asymptotes

y = (2)^{x} - 3

inverse of f(x)=3+2ln(x)inverse

f (x) = 3 + 2 ln (x)

inflection f(x)=5x^4+20x^3 inflection points

f (x) = 5 x^{4} + 20 x^{3}

domain of f(x)=-9x+4 domain

f (x) = - 9 x + 4

range of (1+x^2)/(x^2)range

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