Answer:
3. y = 3·4^x
4. y = 24·0.5^x
5. y = 45·0.9^x
Step-by-step explanation:
Each table appears to represent an exponential function. Such a function can be written in the form ...
y = a·b^x
where 'a' is the value of y when x=0, and 'b' is the ratio of the values of y when x=1 and x=0.
__
3. a = 3. b = 12/3 = 4
y = 3·4^x
__
4. a = 24. b = 12/24 = 0.5
y = 24·0.5^x
__
5. a = 45. b = 40.5/45 = 0.9
y = 45·0.9^x
