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

inverse

f (x) = x^{2} + 2

x^{2} - 2, - x^{2} - 2

Solution steps

y = x^{2} + 2

Replace

x

with

y

x = y^{2} + 2

Solve for

y, x = y^{2} + 2

x^{2} - 2, - x^{2} - 2

\frac{4 x + 8}{3 x - 2}

f (x) = - 4 x + 8

3^{\frac{1}{x}}

f (x) = tan (x + (\frac{7 π}{6}))

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