What is the range of the function ()=12−2 f ( x ) = 1 2 x - 2 when the domain is {2, 4, 6}?

lina2011 [118]

Answer:

{-1, 0, 1}

Step-by-step explanation:

If your function is f(x) = 1/2x -2, then the range is found by executing the function on each of the domain values:

f(2) = 2/2 -2 = -1

f(4) = 4/2 -2 = 0

f(6) = 6/2 -2 = 1

The range is {-1, 0, 1}.
