In an exponential function, what does the 'a' represent? 

• BASE

• RATE OF CHANGE
• INITIAL AMOUNT
• GROWTH OR DECAY FACTOR

What is the asymptote of y = 2^x ?

• y = 0

• x = 0

• x=4

• y=4

• y=2

Does the equation represent an exponential function?

• Yes

• No

Which number is the BASE?
2³ = 8

• 2
• 3
• 8
• not here

• Because the 25 was bigger than one

• Because the 0.20 was bigger than one

• Because the 25 was less than one

• Because the 0.20 was less than one

• Because the 0.25 was bigger than one

• Because the 1.3 was bigger than one

• Because the 0.25 was less than one

• Because the 1.3 was less than one
