Webe^x times 1. f' (x)= e^ x : this proves that the derivative (general slope formula) of f (x)= e^x is e^x, which is the function itself. In other words, for every point on the graph of f (x)=e^x, the slope of the tangent is equal to the y-value of tangent point. So if y= 2, slope will be 2. if y= 2.12345, slope will be 2.12345.
