rate at which a function value changes with respect to change in the variable of the function. Derivative calculator wolfram is an

instant online tool very helpful in finding the derivative of a function and its other details.

Given function: x

Applying the above formula for every term of the function, we get

Derivative of the given function d f(x)/dx= d (x

df(x)/dx = 3*x

df(x)/dx = 3x

Hence the derivative of the function f(x) = x

Given function: 2x

Applying the above formula for every term of the function, we get

Derivative of the given function d f(x)/dx= d (2x

df(x)/dx = 2*2x

d f(x)/dx = 4x

Hence the derivative of the function f(x) = 2x
