Given the domain (-2,2,4) what is the range for the relation 3x-y=3

Given the domain, the range for 3x-y = 3 is {-9, 6, 9}

Step-by-step explanation:

First you have to put the relation in terms of y ⇒ 3x - y = 3⇒ 3x - 3 = y

⇒ y = 3x - 3.

Then you replace the values indicated by the domain to find their "y" values (the ones that constitute the range).

f (-2) = - 9

f (2) = 6

f (4) = 9.

Finally, the range for the given domain is {-9, 6, 9}
