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:

$x = 1\\f (1) = 1-5 = -4\\So, y = -4$ $x = 2\\f (2) = 2-5 = -3\\So, y = -3$ $x = 3\\f (3) = 3-5 = -2\\Thus, y = -2$ $x = 4\\f (4) = 4-5\\f (4) = - 1\\Thus, y = -1$

The price is decreased by $320-$240=$80. This means that the decrease is $80/$320 is 1/4, or 25/100, or 25%.

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
