Question

The following table represents an exponential. The exponential function represented by the table can be written in the form y=ab^x PLZ i really need help 20 points.

Answer 1

a=4 b=1/2

Explanation:

Answer 2

Answer:
`y=4((1)/(2))^x`

Explanation:

The exponential function represented by the table can be written in the form
`y=ab^x`, here a is the initial amount and b is the constant ratio and x is the independent variable.

From the given table, At x=0

`4=ab^0\\\Rightarrow\ a=4`

From the given table, At x=1

`2=4b^1\\\Rightarrow\ b=(2)/(4)\\\Rightarrow\ b=(1)/(2)`

Therefore, the required function will be :-

`y=4((1)/(2))^x`
