I am having trouble using Desmos. I have $22$ data sets forming a parabola, and need to make three sliders. The first is an s slider that needs to be equal to the maximum y$-$value of the dataset. The second slider, t$,$ needs to be equal to the maximum y$-$value of the quadratic regression. $($They are slightly different$)$ and the third slider, u$,$ need to be equal the the percent error betweem these two maximum values. The precent error equation $(\mathrm{.}34,5)(1\mathrm{.}09,10)(4\mathrm{.}27,20)(9\mathrm{.}13,30)(17\mathrm{.}14,40)(26\mathrm{.}54,50)(38\mathrm{.}53,60)(60\mathrm{.}66,70)$

$(85\mathrm{.}13,80)(113\mathrm{.}34,90)(148\mathrm{.}76,100)(170\mathrm{.}9,95)(183,85)(194\mathrm{.}79,75)(205\mathrm{.}96,65)$

$(211\mathrm{.}2,60)(220\mathrm{.}9,50)(229\mathrm{.}19,40)(237\mathrm{.}06,30)(242\mathrm{.}2,20)(243\mathrm{.}9,15)(246\mathrm{.}17,0)$
