Answer:

Set 1

Step-by-step explanation:

To have a function, you cannot have the same x-coordinate more than once.

In sets 2, 3, and 4, all x-coordinates of each set are different, so they are functions.

In set 1, the x-coordinate 1 appears twice, so set 1 is not a function.

Answer:

$\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]$

Step-by-step explanation:

Given

$y = 4x - 1$

Required

Create a function table for inputs -2, 0, 2 and 4

When x = -2

$y = 4*-2 - 1 = -9$

When x = 0

$y = 4*0 - 1 = -1$

When x = 2

$y = 4*2 - 1 = 7$

When x = 4

$y = 4*4 - 1 = 15$

So, the table is:

$\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]$
