The exponential equation modeling this relationship is given as follows:

f(x) = 8(0.5)^x.

What is an exponential equation?

An exponential equation is modeled by:

f(x) = a(b)^x

In which:

  • a is the initial value, that is, the value of y when x = 0.
  • b is the rate of change.

For this problem, we have that when x = 0, y = 8, hence a = 8. Then:

f(x) = 8(b)^x.

When x = 1, y = 4, hence b is found as follows:

f(x) = 8(b)^x.

4 = 8b

b = 0.5.

Hence the equation is:

f(x) = 8(0.5)^x.
