Suppose each of the following tables defines functions completely. Identify which of the tables represents the decreasing function.
\(\begin{array}{|c|c|c|c|c|c|c|c|} \hline x &-1 & -2 & 0 & -3 & 3 & 2 & 1 \\\hline f(x) & 3&4&-1&5&-5&-4&-3 \\\hline \end{array}\)
\(\begin{array}{|c|c|c|c|c|c|c|c|} \hline x &3 & 2 & 1 & 0 & -1 & -2 & -3 \\\hline h(x) & 5&4&3&2&0&-1&-2 \\\hline \end{array} \)
\(\begin{array}{|c|c|c|c|c|c|c|c|} \hline x &-3 & -2 & -1 & 0 & 1 & 2 & 3 \\\hline g(x) & 3&2&1&0&3&2&1 \\\hline \end{array} \)
\(\begin{array}{|c|c|c|c|c|c|c|c|} \hline x &-1 & -2 & 0 & -3 & 3 & 2 & 1 \\\hline m(x) & 3&4&-3&5&-5&-4&-3 \\\hline \end{array}\)

Compare two definite integrals \( I_1 = \int\limits_1^2 \frac1x\,\mathrm{d}x \) and \( I_2 = \int\limits_2^4 \frac1x\,\mathrm{d}x \).
\( I_1 \) is equal to \( I_2 \).
\( I_2 \) is twice as big as \( I_1 \).
\( I_1 \) is twice as big as \( I_2 \).
\( I_1 \) is \( 4 \) times as big as \( I_2 \).

Compare two definite integrals \( I_1 = \int\limits_0^5 0.6x\,\mathrm{d}x \) and \( I_2 = \int\limits_0^5 1.8x\,\mathrm{d}x \).
\( I_2 \) is \( 3 \) times as big as \( I_1 \).
\( I_1 \) is \( 3 \) times as big as \( I_2 \).
\( I_2 \) is \( 1.2 \) multiple of \( I_1 \).
\( I_2 \) is \( 30 \) times as big as \( I_ 1 \).
