Respuesta :
[tex] f(x) = x^2 - 36 [/tex]
[tex] y = x^2 - 36 [/tex]
[tex] x = y^2 - 36 [/tex]
[tex] y^2 = x + 36 [/tex]
[tex] y = \pm \sqrt{x + 36} [/tex]
[tex] f^{-1}(x) = \pm \sqrt{x + 36} [/tex]
[tex] y = x^2 - 36 [/tex]
[tex] x = y^2 - 36 [/tex]
[tex] y^2 = x + 36 [/tex]
[tex] y = \pm \sqrt{x + 36} [/tex]
[tex] f^{-1}(x) = \pm \sqrt{x + 36} [/tex]
