Which table represents a function? a 2-column table with 4 rows. the first column is labeled x with entries negative 3, 0, negative 2, 8. the second column is labeled y with entries negative 1, 0, negative 1, 1. a 2-column table with 4 rows. the first column is labeled x with entries negative 5, 0, negative 5, 6. the second column is labeled y with entries negative 5, 0, 5, negative 6. a 2-column table with 4 rows. the first column is labeled x with entries negative 4, negative 2, negative 2, 0. the second column is labeled y with entries 8, 2, 4, 2. a 2-column table with 4 rows. the first column is labeled x with entries negative 4, 3, 1, negative 4. the second column is labeled y with entries 2, 5, 3, 0.

The 1st table represents a function

Step-by-step explanation:

* Lets explain how to solve the problem

- Function is a relation where each input has a single output

- The notation of the function is f(x) = y , where x is the input of the

 function and y is the out put of the function

-  The domain of the function is x and the range of the function is y

* Lets find which table represent a function

# First table:

      x      y

     -3      -1

      0      0

     -2      -1

- In the first table

∵ -3 has only -1

∵ 0 has only 0

∵ -2 has only -1

∵ 8 has only 1

∵ Every x has a single y

∴ The table represents a function

∴ The 1st table represents a function

- In the second table

    x       y

    -5       -5

     0       0

    -5       5

     6       -6

∵ x = -5 has y = -5 and y = 5

∴ One x has two values of y

∴ The table doesn't represent a function

- In the third table

     x          y

    -4         8

    -2         2

    -2         4

     0         2

∵ x = -2 has y = 2 and y = 4

∴ One x has two values of y

∴ The table doesn't represent a function

- In the fourth table

     x          y

    -4         2

     3         5

    -4         0

∵ x = -4 has y = 2 and y = 0

∴ One x has two values of y

∴ The table doesn't represent a function

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
