Question

Can someone show me how to even start with 1 and 2? ​

Answer 1

All you need to know is that

`\displaystyle \lim_(x\to\infty)a^x=\begin{cases} \infty \text{ if } a>1\\1 \text{ if } a=1\\0 \text{ if } 0\leq a<1\end{cases}`

So, the first function grows exponentially and the second decays exponentially. The rate of growth/decay are the bases of the exponentials, which means 1.08 and 0.205
