We can define the derivative as the slope of the tangent line. It measures the changes in the given function with respect to given variable. We have derivative formula to find the derivatives of functions,



Problem 1: Find the derivative of the function f(x) = 4x.

Solution: Step1: The given function is f (x) = 4x

=> Step2: We can the derivative formula that is


=> So the derivative of 4x is 4.
 

Problem 2: Find the derivative of the function f(x) = 7x + 2.

Solution:  Step1: The given function is f (x) = 7x + 2

=> Step2: We can the derivative formula that is

=> So the derivative of 7x + 2 is 7.
