The Range is the set: { -29, -4, 11 }
Step-by-step explanation:
You need to apply the given function to the x-values of the Domain, to find what values of the Range they are associated with. So let's start by isolating y on one side of the expression:
y = 1 - 5 x
Now let's find what values they result when x = -2, 1, and 6:
y = 1 - 5 (-2) = 1 + 10 = 11
y = 1 - 5 (1) = 1 - 5 = -4
y = 1 - 5 (6) = 1 - 30 = -29
Therefore the Range is the set: { -29, -4, 11 }
