$1.)$ For the function $y=2x^2+3$

$4.)$ In Excel, nist create an $x$ column $($with appropriate header$)$ where $x$ values range from $0$ to $30$ in $0\mathrm{.}5$ increments. There is no need to hand type $0,0\mathrm{.}5,1,$dots$30$ all by hand, which would take a while. Instead, use the following trick type in the first two values, highilight both cells, put your cursor in the lower right comer unut it tums color $($rom fis to $+),$ and then drag down holding the mouse button

II$.)$ Then program a $\text{'}y$ column $($with header$)$ which compuntes the value of $y$ from its III.$)$ Make a graph of $y$ vs$.x($note$,$ this means $x$ is on the horizontal axis.$)$ Please follow along carefully with all of the graphing guidellines $($How to Use Excel, Section $3,$ on p$\mathrm{.}3).$ You do NOT need to do any of the $"$by request' steps isted for today's lab$-$

$2.)$ For the function $z=x^2-c\sqrt[\phantom{2}]{x}$

$1.)$ Please add a third column for $z$ in your spothadsheet. Calculate your $z$ values from the same $x$ value column from above. $11.)$ What to do with the $"c\text{'}$ in the equation

You should use a value of $c=105.$ However, do not just incorporate that number into your equation. Instead pick two emply cells of fiot them $($this is what is actually used in the computations$),$ and in the ofther, type in the letter $"$c$"$ just to keep things nicely labelled and as $10$ read tor chiners

When programming your equation for $z,$ incorporate the c value by pointing to this cell. When Once you have programmed in the $z$ formula, drag it down to calculate the $z$ value for every $x$ value.
