Define a piecewise continuous function, MYFunction such that:

Arguments:

X

Calculations:

If X is less than or equal to $-5\mathrm{.}5$

Y $=0\mathrm{.}2*$X $+4\mathrm{.}1$

If X is greater than $-5\mathrm{.}5$ but less than or equal to $5\mathrm{.}5$

Y $=0\mathrm{.}08*$X$^2+5\mathrm{.}42$

If X is greater than $5\mathrm{.}5$

Y $=-0\mathrm{.}4*$X $+5\mathrm{.}2$

Return the value of Y
