Forums Study Help Maths, science and technology academic help what does f' (x) actually mean? Easier than ever to use, with dark mode included. This discussion is now closed.

The letter, symbol or even word before the (x) is simply a way of allowing you to know which function it is you are talking about. You can define f (x) to be anything you like, the "f" label is …

So I've heard people say f' (x) as "F dash x" and some people say it as "F prime x" I've always thought F prime X was the correct way of saying it and one of my teachers tells students off for …

Original post by hpblcparaboloid f (x) = x^3 + 8x - 19 Show that the equation f (x) = 0 has only one real root Would differentiating it help? No- differentiating helps find the gradient, whilst you're …

May 30, 2024 · If the function you need to integrate is of the form f (ax+b) then you can use the "integrate as normal" approach, that is integrate as though you were integrating f (x) then …

May 15, 2025 · 10) x=5, only answer (reject x=-4) 11a) show that question, just find an equation for A and for V in terms of L and substitute one into the other. b) 44.8cm c) find second …

Feb 19, 2018 · A username3694726 8 Given that for all values of x, f (x) = 3x+p g (x) = px+4 and fg (x) = 6x+q where p and q are constants. Work out the values of p and q.

Jul 9, 2015 · f` (x) = (x − 1/x)^2, > 0 always, or ≥ 0 always Is the answer to the following question: f ′ (x) = x^2 – 2 + x^ (-2). c) Prove that f is an increasing function. I understand the first line of …

My second question is thus about how only knowing f" (x)=0 can lead you to believe that it is a non-stationary point of inflection. Could it not just be any part of the graph, or is non-stationary …

That would be integrating f (x) * g (x) ? I dont think you can, or maybe you can but it would be useless. When you differentiate an implicit function, you are differentiating each term with …
