Určete inverzní funkci f −1 (x) a její definiční obor:
=====16.=====
\(    f(x) = 2x + 3 \)
[[wa>inverse 2x + 3 ]]

=====17.=====
\(    f(x) = x^2, x \leq 0 \)
[[wa>inverse x^2]]

=====18.=====
\( f (x) = x^2, x \geq 0, \)
[[wa>inverse x^2]]

=====19.=====
DELETEME \( f(x) = \sqrt{\frac{1 - x}{1 + x}}, x \neq -1 \)
[[wa>inverse sqrt((1 - x)/(1 + x)), ]]

=====20.=====
DELETEME \( f(x) = \sqrt{1 − x^2} , −1 \leq x \leq 0 \)
[[wa>     (sqrt(1 − x^2))^-1 , x=-1 to 0]]

=====21.=====
DELETEME \( f(x) = \sqrt{1 − x^2} , 0 \leq x \leq 1 \)
[[wa>   sqrt(1 - x^2), (sqrt(1 − x^2))^-1 , x=0 to 1]]
