Question

Which exponential function is represented by the table below? x –2 0 2 4 y 16 4 1 14 A. 4⋅2x B. 14⋅4x C. 4⋅(12)x D. 4⋅(14)x

Answer 1

The exponential function represented by the table is given as follows:

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

What is an exponential function?

An exponential function is modeled by:

$y = ab^x$.

In which:

• a is the initial value.

• b is the rate of change.

Considering the table:

• When x = 0, y = 4, hence a = 4.

• When x changes by 2, y changes by 1/4, hence b = 1/2.

Then the equation is:

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