Answer:

Step-by-step explanation:

This equation is y=4-(x+1)^2, there is no restriction upon x and y has a max value of four and approaches negative infinity as x moves away from -1 in either direction. So the domain is all real numbers and the range is all real numbers less than or equal to four.

The domain and range of the quadratic function are:

  • Domain: Set of all real numbers.
  • Range: y ≤ 4.

How to get the domain and range?

For a function y = f(x), we define the domain as the set of the possible inputs x, and the range is the set of the possible values y.

On the graph, we can see a quadratic function.

For the domain, we usually start assuming that the domain is the set of all real numbers, and then we remove problematic points. Where a problematic point can be a zero on a denominator or something like that.

In the case of a quadratic, there are no problematic points, then the domain is the set of all real numbers.

For the range, we can see that the function has a maximum at y = 4, and then it goes down, so the range is just:

R: y ≤ 4.
