WebSep 7, 2024 · Definition: Derivative Function. 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. WebExample: Find the derivative of x 5. Solution: As per the power rule, we know; d/dx(x n) = nx n-1. Hence, d/dx(x 5) = 5x 5-1 = 5x 4. Sum Rule of Differentiation. If the function is sum or difference of two functions, then the derivative of the functions is the sum or difference of the individual functions, i.e., If f(x)=u(x)±v(x), then; cinthya crespo fong
