How Do You Know If A Piecewise Function Is Continuous And Differentiable

How Do You Know If A Piecewise Function Is Continuous And Differentiable - We examine a piecewise function to determine its continuity and differentiability at an edge point. By analyzing left and right hand limits, we establish continuity. Checking the limit of the difference quotient confirms both left and right hand limits are equal, making the function continuous and differentiable at the edge point.

How Do You Know If A Piecewise Function Is Continuous And Differentiable

Method 1: We are told that g is differentiable at x=3, and so g is certainly differentiable on the open interval (0,5). and . So the two limits both exist and by Theorem 1 must be equal. Hence . Since g is continuous at x=3, 2k=3m+2. This gives the two equations to solve for k and m. Method 2: Let and q (x)=mx+2. Both are differentiable at x=3. x^2 is a parabola centered at the origin....If you take its derivative you get 2x, therefore the derivative of f (x) at 0 would be equal to 0... or you can write as f' (0) = 0....It is a parabola you do not have a hard corner where you would end up with an infinite number of slopes crossing that point......
