Answer:

y (output) = 8

Step-by-step explanation:

In a function, the input is the domain (or the set of x-values), while the output is the range (y-values).  

Given the linear function, y = ⅔x - 4, and you're provided the input value of 18.

Simply substitute 18 as the value of the input, and solve for the input:

y = ⅔x - 4

y = ⅔(18) - 4

y = 2(6) - 4

y = 12 - 4

y = 8

Therefore, the output value is 8.
