WebDifferentiability When working with a function \( y=f(x)\) of one variable, the function is said to be differentiable at a point \( x=a\) if \( f′(a)\) exists. Furthermore, if a function of one variable is differentiable at a point, the graph is “smooth” at that point (i.e., no corners exist) and a tangent line is well-defined at that point. lycamobile mobile offers https://robertabramsonpl.com

In mathematics, a differentiable function of one real variable is a function whose derivative exists at each point in its domain. In other words, the graph of a differentiable function has a non-vertical tangent line at each interior point in its domain. A differentiable function is smooth (the function is locally well approximated as a linear function at each interior point) and does not contain a… WebSep 6, 2024 · Differentiability of a function: Differentiability applies to a function whose derivative exists at each point in its domain. Actually, differentiability at a point is defined as: suppose f is a real function and c is a point in its domain. The derivative of f at c is defined by \(\lim\limits_{h \to 0} \frac{f(x+h) – f(x)}{h}\)
