# How do you find domain and range for #f(x)=(x^2+2x)/(x+1) #?

The domain is

Consequently,

To find the range, follow these steps:

The person who discriminates is

Consequently,

Thus,

x^2+2x)/(x+1) = graph{[-16.02, 16.01, -8.01, 8.01]}

To find the domain of the function, we identify any values of x that would result in division by zero. In this case, the function is undefined when x = -1. Therefore, the domain of the function is all real numbers except x = -1.

To find the range of the function, we consider the behavior of the function as x approaches positive or negative infinity. As x approaches positive or negative infinity, the function approaches the value of 1. Therefore, the range of the function is all real numbers except y = 1.
