These ordered pairs, {(2,4) (3,6) (4,8) (5,10)}, are a function.<br><br> True<br><br> False
ki77a [65]

Answer:

True

Step-by-step explanation:

In order for a relation (a set of ordered pairs) to be considered a <em>function</em>, every value in the <em>domain</em> (the set of all the first numbers in the pair) is associated with one value in the <em>range</em> (the set of all second numbers in the pair). This is easiest to see visually. Our domain is the set {2, 3, 4, 5} and our range is the set {4, 6, 8, 10}, and we can visualize the ordered pair (2, 4) as an "arrow" starting a 2 in the domain and ending at 4 in the range. When seen this way, a relation is a function if <em>every value in the domain only has one arrow coming out of it</em>. We can see from the attached picture that the ordered pairs in the problem are a function, so this statement is true.

What is the answer? What does the symbol mean??
madam [21]

Answer:

6 or -6

Step-by-step explanation:

The symbol √ is the square root symbol.

The square root of a number is a number that when you multiply it by itself you get the first number.

For example:

The square root of 9 is 3 since 3 times itself, 3 × 3, is 9.

The square root of 9 is also -3 since (-3) × (-3) is 9.

The question is asking for the positive and negative square roots of 36.

What number multiplied by itself is 36?

The answer is 6 since 6 × 6 = 36 and -6 × -6 = 36

Answer: 6 or -6
