Para cada uma das funções a seguir, determine seu domínio e decida se a função é ímpar, par ou nenhuma das duas coisas.

(A) \(f(x) = \frac {x}{\sqrt {16-x^2}}\)
O domínio de \(f\) é \(\left (\class{xm-answer}{\cssId{xm-answer-1}{\phantom{\rule{7em}{1.5em}}}},\class{xm-answer}{\cssId{xm-answer-2}{\phantom{\rule{7em}{1.5em}}}}\right )\).

\(f\) is odd. \(f\) is even. \(f\) is neither.

(B) \(f(x) = \frac {x^4}{\sqrt {16-x^2}}\)
O domínio de \(f\) (da esquerda para a direita) é \(\left (\class{xm-answer}{\cssId{xm-answer-3}{\phantom{\rule{7em}{1.5em}}}},\class{xm-answer}{\cssId{xm-answer-4}{\phantom{\rule{7em}{1.5em}}}}\right )\).

\(f\) is odd. \(f\) is even. \(f\) is neither.

(C) \(f(x) = \pi \)
O domínio de \(f\) é \(\left (\class{xm-answer}{\cssId{xm-answer-5}{\phantom{\rule{7em}{1.5em}}}},\class{xm-answer}{\cssId{xm-answer-6}{\phantom{\rule{7em}{1.5em}}}}\right )\).

\(f\) is odd. \(f\) is even. \(f\) is neither.

(D) \(f(x) = e^{1-x^2} + 7\)
O domínio de \(f\) é \(\left (\class{xm-answer}{\cssId{xm-answer-7}{\phantom{\rule{7em}{1.5em}}}},\class{xm-answer}{\cssId{xm-answer-8}{\phantom{\rule{7em}{1.5em}}}}\right )\).
