The length of a rectangle is 4 units greater than its width, and the area of the rectangle can be expressed by the equation y=xsquared +4x. what is a resonable domain for this function?

The domain of the function is

Step-by-step explanation:

Given : The length of a rectangle is 4 units greater than its width, and the area of the rectangle can be expressed by the equation

To find : What is a reasonable domain for this function?

Solution :

Domain is defined as the all possible set of values in which function is defined.

We have given the area,

We know, Area will never be negative so the value of x is always positive.

So,

i.e. Either

or

but x>0

So, The value of x is defined from 0 to infinity.

The domain of the function is
