To determine

To calculate: The value of $\underset{t\to +\infty }{\lim }F\left(t\right)$ and $\underset{t\to +\infty }{\lim }\frac{F\left(t\right)}{Y\left(t\right)}$, if the popularity of Facebook and YouTube among social media sites from $2008-2013$ is approximated as function of time as $F\left(t\right)=-2t^2+16t+35$ percentage points for twitter and as $Y\left(t\right)=-t^2+6.5t-1.8$ percentage points for LinkedIn and also interpret the answer.
