Question is:
Let f(x) be the function $\displaystyle 2 + x^2 + \tan((1/2){\pi}x)$ on -1 < x < 1.
Evaluate for: $\displaystyle f^{-1}(2)$
and $\displaystyle f(f^{-1}(2))$
Question is:
Let f(x) be the function $\displaystyle 2 + x^2 + \tan((1/2){\pi}x)$ on -1 < x < 1.
Evaluate for: $\displaystyle f^{-1}(2)$
and $\displaystyle f(f^{-1}(2))$
since $\displaystyle f(0) = 2$ , $\displaystyle f^{-1}(2) = 0$
