I'm having trouble using the quotient rule of the derivative (i know how to do the power rule though). I'm not sure how I simplify in order to get the final answer/derivative. I need to use it in order to solve my question.
i need to determine the points at which the graph of the function
f(x)= (x^2)/(x-1) has a horizontal tangent.
what i think that i have to do is find the derivative of the function. then find the values of x by letting the derivative equal 0. then find the y values of the new x values by plugging them into the original equation. Am I right?
Yes, find the derivative and set it to zero. The quotient rule looks like this:
Do you understand how to apply this formula? I know it's difficult to remember at first, but you'll get use to it. If you have trouble applying it, I'll show you how. But see if you can do it first.
