Determine if each set of ordered pairs represents a function.
(2, 3), (6,-5), (-1,3)
(1,,-2) (1.4)
7,-4), (0,9), (2,-2)
(0,3), (0,7). (4.0)
(-6,, 6), (8, 2)

In a function: A set of ordered pairs should not be repeating the value of x.

(2, 3), (6,-5), (-1,3) is a function.

(1,9).(-3,-2) (1,4) is not a function. It has a repeating x value.

(0,3), (0,7). (4,0) is not a function. It also has a repeating x value.

(-6,5),(-5, 6), (8, 2) is a function.

answer: b i think

step-by-step explanation:

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
