    there is no y intercept because you cannot plug in x = 0

    ln(0) is undefined

    to find the x intercept, solve 3ln(x)-9=0 for x

    like I said, ln(0) is undefined so there is no y intercept

    3ln(x)-9=0 3ln(x)-9+9=0+9 3ln(x) = 9 3ln(x)/3 = 9/3 ln(x) = 3 x = e^3 x = 20.0855369 so the x intercept is approximately 20.0855369 this means the graph crosses the x axis at about (20.0855369, 0)
