Question

In which table(s) does y vary directly with x? Check all that apply. A 2-column table with 4 rows. Column 1 is labeled x with entries 1, 3, 6, 7. Column 2 is labeled y with entries 3, 9, 18, 21. A 2-column table with 4 rows. Column 1 is labeled x with entries negative 4, negative 2, 2, 6. Column 2 is labeled y with entries negative 2, negative 1, 1, 3. A 2-column table with 4 rows. Column 1 is labeled x with entries negative 2, negative 1, 2, 5. Column 2 is labeled y with entries 2, 1, negative 2, negative 5. A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 0, 1, 2. Column 2 is labeled y with entries 0, negative 1, negative 2, negative 3.

Answer 1

- Lets look to the table of the function

    x            f(x)

    -4           18

    -3            9

    -2            6

    -1             3

     0            0

     1            -3

     2           -6

     3           -9

     4           -18

* From the table we notice that

- The values of x from -4 to zero have positive values of f(x)

- The values of x from 0 to 4 have negative values of f(x)

∴ When x increased from negative to positive y decreased from

 positive to negative

- That means when x values go to -∞ the corresponding values of

 f(x) go to +∞ and when x values go to +∞ the corresponding values of

 f(x) go to -∞

∴ The end behavior of the graph of f(x) is

- When the values of x ⇒ -∞, f(x) ⇒ +∞

- When the values of x ⇒ +∞, f(x) ⇒ -∞

Answer 2

Its the first 3 tables.

I just had the question on Edgenuity
