Warm Up

Which one doesn’t belong?

$f (n) = 8 \cdot 2^{n}$

$g (n) = 2 \cdot 8^{n}$

$h (n) = 8 + 2 n$

$j (n) = 8 \cdot (\frac{1}{2})^{n}$

Compare your answer:

$f$ is the only one that doubles when $n$ increases by 1.

$g$ is the only one that does not have 8 for its vertical intercept.

$h$ is the only one that is not an exponential function.

$j$ is the only one that is not increasing.
