an asymptote
100
In a single elimination tournament starting with 128 teams, half of the remaining teams are eliminated each round. Linear or Exponential?
Exponential
100
Does the table display exponential or a linear model?
Linear; Data has a constant rate of change.
100
Does the graph represent exponential growth or exponential decay?
Exponential decay
100
In an exponential equation, if the base "b" is bigger than 1, then the graph will display exponential decay.
False! If the base "b" is greater than 1, then it will be exponential growth!
200

a
200
You play musical chairs where you begin with 32 chairs and you remove 2 chairs each round. Is this Linear or Exponential?
Linear! Constant rate of change.
200
Linear or exponential: It costs 40 dollars to join a gym and an additional $10 per month.
Linear
200
Does the equation below represent exponential growth or exponential decay?
y=0.5^x
Exponential decay because the base is 0.5 which is less than 1!
200
In an exponential equation, if the base "b" is between 0 and 1, then the graph will display exponential decay.
True! If "b" is between 0 and 1, the graph will be an exponential decay graph!
300
On an exponential graph, the multiplier that divides the y-coordinates of two consecutive points will be determined from which variable in the Exponential equation: y = a bx ?
b
300
A $7,000 car depreciates at a rate of 8.3% per year. Linear or Exponential?
Exponential.
300
Does the table display exponential or a linear model? 
Exponential; data does not have a constant rate of change, the y-values double (multiply by 2) each tim.
300
Does the equation below represent exponential growth or exponential decay?
y=5(2)^x
Exponential growth because the base is 2 and that is greater than 1!
300
The number of chickens on the farm increases by 3% each year. This is an example of exponential growth.
True!!!
400
In an exponential equation, the starting value determines which of the following:
A: the steepness of the graph
B: whether the graph is growth or decay
C: whether the graph is reflected
D: whether or not there is an asymptote
C (a negative "a"-value flips the graph)
