Answer: B 
Step-by-step explanation:
From the given table
When x changes from 1 to 2 , value of y changes from 6 to 4
The multiplicative rate of change=
Similarly we can check
When x changes from 2 to 3 , value of y changes from 4 to 
The multiplicative rate of change=
When x changes from 3 to 4 , value of y changes from
to 
The multiplicative rate of change=
Therefore, the multiplicative rate of exponential function = 
Answer:
Answer:
18 cups.
Step-by-step explanation:
We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation: .
