Question

The domain of the following relation: R: {(3, −2), (1, 2), (−1, −4), (−1, 2)} is

Answer 1

domain is all real numbers

Answer 2

{−1, 1, 3}

{−1, −1, 1, 3}

{−4, −2, 2, 2}

{−4, −2, 2}

Answer 3

thats what i have to pick from

Answer 4

Step 1 : Given function is x2-2.

Step 2 : The set of entire real numbers will be the domain of the given function and the range will vary based of the function f(x). Since we assumed the value of x as rel number, x2 value will become zero or above. Hence x2 > = 0. subract 2 from both sides to get the desired expression. Hence the Range will exist above -2.

Answer : Domain R ( all real numbers) Range {ybelongs to R: y>= -2}

Answer 5

But thats not on here so what do i do

Answer 6
