 The exponential function form f(x)=a^x 2012-08-13 From Lucy:Hi, Why does the "a" value in the exponential function form f(x)=a^x have to be negative?Answered by Penny Nom. What is the derivative of (2^sinx)/(logbase4(2x+1))? 2008-09-16 From Jesse:What is the derivative of (2^sinx)/(logbase4(2x+1))Answered by Harley Weston. Graphing F(x) = 3x 2000-11-06 From Jose:graph the exponential problem F(x)=3xAnswered by Harley Weston. Functions that satisfy f' = f 2000-03-16 From Kevin Palmer :Recently my calculus teacher asked his students to try and find any functions whose derivatives where the exact same as the original function. The only function then I have determined that statement to be accurate in is all the natural exponential functions. Ex. f(x) = ex, f'(x) = ex If possible could you please email me all the functions that you can find in which the original function and its derivative is identical. Answered by Claude Tardif.
