Question

Use the function rule. Find y for x = 1, 2, 3, and 4. y = x – 5

-y = 4, 3, 2, 1
-y = 6, 7, 8, 9
-y = –5, –4, –3, –2
-y = –4, –3, –2, –1

Answer 1

is the fourth one

Explanation:

just replace x with the numbers given

and then work it out.

y=x-5

y=1-5=-4

y=2-5=-3

and so on

hope this helps

Answer 2

For this case we have a function of the form
`y = f (x)`where:

`f (x) = x-5`

We must find the values of "y" when
`x = 1,2,3,4`

Then, keeping in mind that different signs are subtracted and the sign of the major is placed:

• 
  `x = 1\\f (1) = 1-5 = -4\\So, y = -4`

• 
  `x = 2\\f (2) = 2-5 = -3\\So, y = -3`

• 
  `x = 3\\f (3) = 3-5 = -2\\Thus, y = -2`

• 
  `x = 4\\f (4) = 4-5\\f (4) = - 1\\Thus, y = -1`
