So far so good? Heres a list of native, unary statistical commands supported in Desmos: Additionally, heres a list ofbinary statistical commands supported in Desmos, with slightly more delicate syntax: To be sure, the fact that these are about the only native commands supported in Desmos doesnt mean that these are the only statistical measures we are restricted to. \], so \(n=3.\) Therefore, \( r=\frac13\) and \( x = n+r = \frac{10}3.\) \(_\square\), Find the smallest positive real \(x\) such that \(\big\lfloor x^2 \big\rfloor-x\lfloor x \rfloor=6.\) If your answer is in the form \(\frac{a}{b}\), where \(a\) and \(b\) are coprime positive integers, submit your answer as \(a+b.\). Solve pant limg f (x) by using tables (provide those tables of your solution) Solve Wms' f(x) by using tables (provide those tables part of your solution). However, all is not lost though, as Desmos will display the coordinates of the x-intercepts if you click on them on the graph. No need to ever redo the $x$-values over and over again! You can do this by making a slider on the graph. \] 1-1- 20. Traditionally, the most popular functions are the ones expressed in terms of $x$, which can be typed into a command line as follows: \begin{align*} y = \text{some algebraic expressions in terms of }x \end{align*}. where \( \lfloor \cdot \rfloor \) denotes the greatest integer function. Alternatively, if a function has already been assigned a name, we can alsouse the prime notation to denote itsderivative function (as in $f'(x)$).
