The length of a rectangle is 4 units greater than its with ,and the area of a rectangle can be expressed by the equation y= x^2+4x. Wha tins the reasonable domain for this function

all real numbers

Step-by-step explanation:

The domain are the values of the input values x that makes the given function exist

Given the function:

y= x^2+4x

Since x^2 is a perfect square, the value of x can exist on all real numbers

Hence the domain of the function is all real numbers

answer: t=3

step-by-step explanation:

i think asking google will you get the answer to that question
