Answer

\(\boxed{y = 1.3e^{-1.204x}}\)

Steps

Step 1 :The given equation is in the form of an exponential function with base 0.3. We can rewrite this in terms of base e by using the property of logarithms that states \(a^b = e^{b \ln a}\). Therefore, we can rewrite the equation as \(y = 1.3e^{x \ln 0.3}\).

Step 2 :Calculate the natural logarithm of 0.3, which is approximately -1.204.

Step 3 :Substitute this value into the equation to get the final answer.

Step 4 :\(\boxed{y = 1.3e^{-1.204x}}\)
