Question 1060401: Given the function
f(x)=0.2e^0.9x
Find it's inverse
State the domain
Graph both functions on the same set of axes
Answer by CubeyThePenguin(3113) (Show Source): You can put this solution on YOUR website!
y = 0.2e^(0.9x)
5y = e^(0.9x)
ln(5y) = 0.9x

ln(5y)/(0.9) = x

(domain is x > 0)
