Step-by-step explanation:
X+3 =2X +1
X= 2
sides,,5,5 ,6 ft
perimeter = 5+5+6 = 16
Derivative Functions
The derivative function gives the derivative of a function at each point in the domain of the original function for which the derivative is defined. We can formally define a derivative function as follows.
Definition:
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:
