Derivative of 2x

The derivative of 2x is equal to 2 as the formula for the derivative of a straight line function f(x) = ax + b is given by f'(x) = a, where a, b are real numbers. Differentiation of 2x is calculated using the formula d(ax+b)/dx = a. We can also evaluate the derivative of 2x using the differentiation power rule which has the formula d(xⁿ)/dx = nx^n-1. Derivative of 2x can also be determined using other methods of differentiation.

Further in this article, we will evaluate the derivative of 2x using various differentiation methods and its formula. We will prove the differentiation of 2x and go through some solved examples involving the derivative of 2x for a better understanding of the concept.

The derivative of a function gives the rate of change in that function with respect to the change in the variable. For a linear function f(x) = ax + b, the derivative is a constant function. Hence, the derivative of 2x is a constant which is given by 2. We can evaluate the derivative of 2x using different methods of differentiation such as the power rule, product rule, first principle of derivatives, and the derivative of linear function formula. Also, as we know that the derivative of kx is equal to k, therefore it follows that the derivative of 2x is 2. Let us now see the formula for the differentiation of 2x.

The formula for the derivative of 2x is given by d(2x)/dx = 2. We can compute the differentiation of 2x using the fact that the derivative of f(x) = kx is equal to f'(x) = k. Using this, we can say that the derivative of 2x is equal to 2. The image below shows the formula for the differentiation of 2x:

Now that we know that the derivative of 2x is equal to 2, we will derive this using various rules of derivatives. We can derive the formula using the definition of derivatives using limits, power rule, product rule, and the derivative of f(x) = ax + b formula.

Derivative of 2x Using Limits

To derive the derivative of 2x using the first principle of derivatives, we will use the following formulas:

• d(f(x))/dx = lim_h→0 [f(x+h) - f(x)]/h
• lim_h→0 k = k, where k is a constant

d(2x)/dx = lim_h→0 [2(x+h) - 2x]/h

= lim_h→0 [2x + 2h - 2x]/h

= lim_h→0 [2h]/h

= lim_h→0 2

= 2

Hence, the derivative of 2x is equal to 2 using the first principle of derivatives.

Differentiation of 2x Using Power Rule

The power rule of differentiation states that the derivative of x to the power n is given by n times x to the power n minus 1, that is, d(xⁿ)/dx = n x^n-1. We will also use the derivative rule of scalar multiple of a function, that is, d(kf(x))/dx = kd(f(x))/dx. Therefore, we have d(2x)/dx = 2 dx/dx = 2. Hence, the differentiation of 2x is equal to 2.

Derivative of 2x Using Product Rule

The product rule of differentiation is used to find the derivative of the product of two or more functions. If we have h(x) = f(x)g(x), then the derivative of h(x) is given by, h'(x) = f'(x) g(x) + f(x) g'(x). Similarly, for h(x) = 2x, we have f(x) = 2 and g(x) = x. Using the product rule, we have,

(2x)' = (2)' × x + 2 × (x)'

= 0 × x + 2 × 1

= 2

Therefore, we have that the derivative of 2x is 2 using the product rule.
