Answer:

C

Step-by-step explanation:

For a relation to be a function then every value of x must map to exactly one unique value of y.

Here every x- value corresponds to exactly one y- value

Then the ordered pairs represent a function

The graph of the step function g(x) = –⌊x⌋ + 3 is shown.
Blababa [14]

Using it's concept, the domain of the function is given as follows:

{x| –2 ≤ x <= 5}

<h3>What is the domain of a function?</h3>

The domain of a function is the set that contains all possible input values for the function, that is, the values for which the function is defined.

The function described in this problem is defined from x = -2 until x = 5 hence the domain of the function is given as follows, by the interval:

{x| –2 ≤ x <= 5}

What is the range of the function?
AleksAgata [21]
The range of the function on the graph is all real numbers greater than or equal to 2 because the range of a function is what the value of y could be, and y begins at 2 and keeps increasing indefinitely.
Hope this helps!

ss7ja [257]

Answer:

a difference of squares

Step-by-step explanation:

Let's write down the expression:

(a^2)^2 -(b^2)^2

we can see that this expression is one of the form x^2 -y^2 which is the general expression of a difference of squares.

To be more specific and to see why we say this, let's make x=a^2 and y=b^2

Now, if we substitute this in the general formula, we get:

x^2 -y^2 =(a^2)^2 -(b^2)^2

Thus, this expression is a difference of squares.
