For more intricate graphs, you can also use inequalities with restrictions to shade selected parts of the graph. Definition: A function is a relation between a set of inputs and outputs where, for every input, there is one (and only one) output. In fact, we could , for example, evaluate the range of a list $a$ by using the command max(a) - min(a),and calculate the Inter-Quartile Range by using quantile(a,0.75) - quantile(a,0.25). It's my first time to use it but extremely satisfied with such explanation. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? Because you might remember this thing called theTexas Instrument TI-83from the old days. 1. Of course, the restriction could have been an inequality on$y$ as well, as in the graph of the function $x^2$ where $y$ is restricted to the interval $[5,15]$: \begin{align*} y=x^2 \, \{ 5 \le y \le 15 \} \end{align*}.
