What is the decay factor of the exponential function
represented by the table?

Given:

The table of values of an exponential function.

To find:

The decay factor of the exponential function.

Solution:

The general form of an exponential function is:

             ...(i)

Where, a is the initial value and is the decay factor and is the growth factor.

The exponential function passes through the point (0,6). Substituting in (i), we get

The exponential function passes through the point (1,2). Substituting in (i), we get

Here, lies between 0 and 1. Therefore, the decay factor of the given exponential function is .

Hence, the correct option is A.

18 ft

Step-by-step explanation:

The area of a rectangle is given by

A = l*w

144 = 8w

Divide each side by 8

144/8 =w

18 =w
