Exponential Growth and Decay

Can somebody please check my answers?
1. Identify the initial amount a and the growth factor b in the exponential function.

g(x)=14*2^x
a)a=14, b=x
b)a=14, b=2 <<<<
c)a=28, b=1
d)a=28, b=x

2. Identify the initial amount a and the growth factor b in the exponential function.

f(t)=1.4^t
a)a=1, b=0.4
b)a=1.4, b=0<<<<
c)a=1.4, b=t
d)a=1, b=1.4

3.Find the balance in the account after a given period.
$4000 principal earning 6% compounded annually, after 5 years.

a)$6,726.28
b)$5,352.90<<<<
c)$5,395.40
d)$7,716.74

6.Identify the initial amount a and the growth factor b in the exponential function.

y=5*0.5^x

a)a=5, b=x
b)a=0.5, b=5
c)a=5, b=0.5<<<<<
d)a=0.5, b=x

11. State whether the equation represents exponential growth, exponential decay or neither.

  1. #1 ok
    #2 initial amount is 1.4^0=1
    #3 ok
    #6 ok
    #7 ok

    I'm surprised you blew it on #2; the others indicate good understanding.

    What do you think b=0 would indicate?

  30. Be careful of these lists of answers without explanations. Sometimes kids deliberately post wrong answers. Sometimes teachers and/or test publishers mix the questions and answer choices up. Sometimes they change them completely!

    Actually, I had got these answers correct, but I came here to double check my work. Zolita is 100% correct. I want to thank her for her help, since, as you know, there are some people who -- just -- do not -- HELP.
