Working with exponential functions

  1. Sep 12, 2010 #1
    1. The problem statement, all variables and given/known data
    Write the function for each graph described. Exponential function with y-intercept of 3 and horizontal asymptote of y=0


    2. Relevant equations
    None

    3. The attempt at a solution
    I used the base equation f(x)=a^(x+h) + k to get f(x) = 3^(x+1)

    Was this right? Also, I used guess and check to solve this is there a better thought process I could use?

    Well that satisfies the conditions. You could have also had f(x)=3ex.
