I am trying to take a derivative of the function below with respect to X. The problem is X is both in the numerator and in the exponential function in the denominator. I don't know how to get the .4X-7.8 out of the exponential function and then combine with the 16X to simplify and take a derivative? I was trying to use ln() somehow but can't seem to figure it out. Thanks!
Thanks! However the X variable is still in the exponent of the exponential function. The 2nd part of this question is to find the value of X that maximizes the function - this is a profit function. So I am trying to take the derivative of f(x) and then solve for X. How do I get the 0.4X out of the exponent?
