I need help on problem $2$ and how to keep it separate from question $1,$ but still on the same script file.

a$)$ Create an anonymous function called my$\_$function equal to

$y=-x^2-5x-3+e^x$

b$)$ Evaluate the function at $x=2.$

c$)$ Use the fplot command to create a plot from $x=-5$ to $x=+5.$ This should give you an

idea of initial guess$($es$).$

d$)$ Find the zero$-$crossing point$($s$)$ within the bound given in part $($c$).$ Display the

answer$($s$)$ in the command window.

e$)$ Find the local minima and the local maxima within the given bound.

The relationship between time, $t,$ and height, $h(t),$ of a rocket ship is

$h(t)=-\frac{g}{2}{t}^2+125t+500$ for $t>0$

a$)$ Create an anonymous function to calculate the height and evaluate height at $20$

seconds. $g=9\mathrm{.}8m{s}^{-2}.$

b$)$ Use the fplot command to plot height vs$.$ time for the valid height values only. $[$hint:

height and time can't be negative values.$]$

c$)$ Find the ground time of the rocket ship.

d$)$ Find the time at which the maximum height occurs and the maximum height with

respect to the ground.

$[$GA: Please check to see if both the graphs are visible when codes are executed. If the graphs are

not available then assign a 'zero' for the rest of the problem.$]$
