<h2>Answer:</h2>

The domain of the function is =

                  C.   (- ∞, ∞)

The range of the function is =

                   B.    [-3, ∞)

<h2>Step-by-step explanation:</h2>

Domain of a function--

It is the set of all the x-values or the values of the independent variable for which a function is defined.

Range of a function--

It is the set of all the values which are attained by a function i.e. it is the set of all the values taken by the dependent variable.

The graph of an absolute value function opens up and has a vertex of (0,-3).

We know that the absolute function is defined  for all the values of x i.e. the domain is the set of all the real values.

Hence, the domain is the set: (-∞,∞)

Also, the graph opens up.

This means that the function takes all the values above -3 and including it.

Hence, the range is : [-3,∞)

Absolute value function domain is all real numbers

absolute value has vertex of(0,-3)
and it opens up
means that the lowest y value is -3
highest is infinity


domain=-inifnity to infinity
range=-3 to positive initnify

the answer is C for the domain and B for the range

A paragraph proof is a two-column proof in sentence form.

Step-by-step explanation:

  • In a paragraph proof, statements and their justifications are written in sentences in a logical order.
  • A two-column proof consists of a list statements and the reasons the statements are true.
  • A paragraph proof is a two-column proof in sentence form.

A paragraph proof is only a two-column proof written in sentences. However, since it is easier to leave steps out when writing a paragraph proof.

A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true. The statements are listed in a column on the left, and the reasons for which the statements can be made are listed in the right column
