hey. the directions say identify the initial amount "a" and the growth factor "b" in each exponential function. i've looked at the examples given and i still don't understand. the first problem is

g(x)=20x2^x

or g(x) equals twenty times two to the "x" power....

i have no idea how to do this... please help me!!!
