Question 1153894
{{{f(x) = tanh(x^2)-1}}}


Alternate form assuming {{{x}}} is real:


{{{f(x) = sinh(x^2)/cosh(x^2) + 1) - 1}}}



The domain of a function is: {{{R}}} (all real numbers)

interval:

({{{-infinity}}}, {{{infinity}}})

range:

y-intercept is ({{{0}}},{{{ -1}}} )

so, range is :{ {{{f(x) }}}element {{{R}}} :{{{ -1<=f<0}}} }
