How do you find the derivative of a function?

How does the derivative of a function help you find its range?

  • for example the function is (2x) ------ sq rt(x^2+x+1) and the derivative is (x+2) ------------------------ (9x^2+x+1)^(3/2) Using the derivative how do you find the range?

  • Answer:

    If you solve for df/dx = 0, you will get the x values for which the function has relative maxima and minima. The largest maxima and smallest minima constitute the range for the function.
