Creating plots: Consider the function f$($v$)$ where v is the velocity in m$/$s$,$

f$($v$)=0\mathrm{.}25$v

$2$

$450+[$log$($v$)]2\mathrm{.}5$

$0\mathrm{.}023$v $9\mathrm{.}8(1)$

Write a script file m that does the following that generates a plot of f$($v$)$ vs v for velocities

from $50$ to $250$ m$/$s$.$

$($a$)$ Plot the x$-$ and y$-$labels and put an appropriate title. Use font of alteast $21.$ Also, ensure

that the x$-$ and y$-$ axis have numbers in fontsize of $12$ or more. $($NOTE: You will have

to search how to change the font size$)$

$($b$)$ Use the plot to estimate where the function f$($v$)$ crosses the x$-$axis. If it does not cross

the x$-$axis then simply state that it does not cross the x$-$axis. The answer to this question

should be printed when the code is run in Octave
