P$9.$ Write a MATLAB script that will create a linear sequence of $250$ values ranging from $-1$ to $1.$

This sequence can be named $x.$ Then, from $x,$ which is also an array, create another array $y$ that

has the values: $y=1-x^3.$ Then, plot $y$ versus $x.$ Label the $x-$axis with the string $\text{'}x\text{'},$ and the $y-$

axis with the string $\text{'}y\text{'}.$ Set the font size to $14.$
