What is the value of $$\frac{2p + 3q}{3p + 2q}?$$
I. $$\frac{p}{q} = \frac{2}{5}$$
II. p and q are positive numbers
For the function $$f : R \rightarrow R$$, is $$f\left(-\frac{1}{2}\right) = f\left(\frac{1}{2}\right) = f(2) ?$$
I. $$f(x) = \begin{cases}-x & for & x < 0\\x & for & x \geq 0\end{cases}$$
II. $$f(x) = \begin{cases}-x & for & x < 0\\x & for & 0 \leq x \leq 1\\\frac{1}{x} & for & x > 1\end{cases}$$
