Is the function differentiable

Witryna26 paź 2024 · If f(x) is differentiable at c then by definition, f ′ (c) = lim h → 0f(c + h) − f(c) h. Similarly, since g(x) is differentiable at c, then g ′ (c) = lim h → 0g(c + h) − g(c) … Witryna25 gru 2015 · HINT: in general a function say y = f ( x) is said to be differentiable at any point x = a iff. left hand derivative = right hand derivative. lim h → 0 − f ( a + h) − f ( a) h = lim h → 0 + f ( a + h) − f ( a) h. or. lim h → 0 f ( a − h) − f ( a) h = lim h → 0 f ( a + h) − f ( a) h.

Why can a discontinuous function not be differentiable?

WitrynaYes, you can define the derivative at any point of the function in a piecewise manner. If f (x) is not differentiable at x₀, then you can find f' (x) for x < x₀ (the left piece) and f' (x) for x > x₀ (the right piece). f' (x) is not defined at x = x₀. If f is differentiable at a point x0, then f must also be continuous at x0. In particular, any differentiable function must be continuous at every point in its domain. The converse does not hold: a continuous function need not be differentiable. For example, a function with a bend, cusp, or vertical tangent may … Zobacz więcej In mathematics, a differentiable function of one real variable is a function whose derivative exists at each point in its domain.

WitrynaWell, it turns out that there are for sure many functions, an infinite number of functions, that can be continuous at C, but not differentiable. So for example, this could be an … Witryna18 maj 2016 · Thus we say f ′ ( z) doesn't exist, and the function is not differentiable. More informative and intuitevely plausible answer for a novice than mine. (+1)! So it is not differentiable. Another way to see it, it is that the real part of a complex number can be written with its conjugate: R e ( x) = 1 2 ( x + x ∗).
