Sample problems

Show your work in the space provided. An exponential function has the form $f (x) = a \cdot b^{x}$ , where $a$ is the initial value and $b > 0$ is the growth ( $b > 1$ ) or decay ( $0 < b < 1$ ) factor.

1. In the function $f (x) = 6 \cdot 4^{x}$ , identify the initial value $a$ and the base $b$ .
2. Does $g (x) = 250 \cdot (\frac{4}{5})^{x}$ represent exponential growth or decay? How can you tell?
3. Evaluate $f (x) = 5 \cdot 2^{x}$ when $x = 4$ .
4. Evaluate $f (x) = 3 \cdot 2^{x}$ when $x = - 2$ .
