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

Answer: $y=4(\frac{1}{2})^x$

Step-by-step 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

$2=4b^1\\\Rightarrow\ b=\frac{2}{4}\\\Rightarrow\ b=\frac{1}{2}$

Therefore, the required function will be :-

$y=4(\frac{1}{2})^x$

Answer 2

Answer:

a=4 b=1/2
