Can piecewise functions be differentiable

WebI think what you want to know is whether a piecewise function can be differentiable on its domain, or in particular at the points where its pieces connect. The answer is sure it can. Assuming that the pieces are … WebDifferentiability of Piecewise Functions - Calculus. In this video, I go through 3 examples, showing how to verify that a piecewise function is differentiable.

Differentiability/continuity of piecewise defined functions

WebFeb 17, 2024 · So for differentiability of the function at $x=1$, we must have both $$a+b=e\tag1$$ $$1+2a+b=e\tag2$$ Solving this, we have $a=-1$ and $b=e+1$. So the function will be differentiable only for $a=-1$ and $b=e+1$. Hence, the option $(2.)$ is … WebOct 19, 2024 · The teacher's trick worked because the left and right functions are both differentiable everywhere, so for the piecewise function to be differentiable the left and right quotient limits must be equal. – copper.hat Oct 19, 2024 at 5:15 1 Because the left-hand limit of the derivative doesn't exist but the left derivative does. – David K graphics driver uninstall tool https://e-healthcaresystems.com

How Do You Determine if a Function Is Differentiable?

WebApr 8, 2024 · A piecewise-defined function is one that is described not by a one (single) equation, but by two or more. Take into account the following function definition: F ( x) = { − 2 x, − 1 ≤ x < 0 X 2, 0 ≤ x < 1. Above mentioned piecewise equation is an example of an equation for piecewise function defined, which states that the function ... WebOct 15, 2016 · A piecewise continuous function doesn't have to be continuous at finitely many points in a finite interval, so long as you can split the function into subintervals such that each interval is … WebCorrect -- that function can not be differentiated at x=-3, which is a removable discontinuity — i.e. your function is not defined at that point.

WebMar 30, 2024 · Find m and b so that the function. f ( x) = { m x + b, if x &lt; 2, x 2, if x ≥ 2. is differentiable everywhere. Hi. I wonder why we cannot solve the following problem as follows: If f is differentiable everywhere, then it is continuous everywhere, so it must be b = 4 – 2 m. Also m = 2 x at x = 2 (taking derivative of each of the pieces). WebAt x = 1, the composite function f (g (x)) takes a value of 6 . At x = 1, the slope of the tangent line to y = f (g (x)) is 2 .

WebApr 24, 2024 · I know that for a function to be differentiable at a point it first has to be continuous at that point and secondly the limit of the derivative must exist at that point so for this case we want 2 things: lim x → 1 − f ( x) = f ( 1) = lim x → 1 + f ( x) lim x → 1 − x n = 1 = lim x → 1 + a x + b a + b = 1. WebSep 7, 2024 · Let f be a function. The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h. A function f(x) is said to be differentiable at a if f ′ (a) exists. More generally, a function is said to be differentiable on S if it is ...

Web2 Answers Sorted by: 3 To prove that a function is differentiable at a point x ∈ R we must prove that the limit lim h → 0 f ( x + h) − f ( x) h exists. As an example let us study the differentiability of your function at x = 2 we have f ( 2 + h) − f ( 2) 2 = f ( 2 + h) − 17 h Now if h &gt; 0 we have the right-side limit
