$\displaystyle f(y) = \left\{ \begin{array}{rcl}

0.2 & \mbox{for} & -1 < y \leq 0 \\

\\

0.2 + cy & \mbox{for} & 0 < y \leq 1 \\

\\

0 & \mbox{} & elsewhere

\end{array}\right.$

I'm not sure exactly sure on how to find it, is it:

1) $\displaystyle \int^{0}_{-1} 0.2 \ \ dy + \int^{1}_{0} 0.2 + cy \ \ dy $ , or

2) $\displaystyle \int^{1}_{0} 0.2 + cy \ \ dy$
