Answer:

{2, 4, 6}

Step-by-step explanation:

that is very simple.

the domain is the interval of set of the valid x (input) values.

we have been given the functional definition and the domain.

the range is the interval of set of valid y (result) values.

we only need to use the given x values and see the y values produced. that is then the range.

x = -1

y = 2×-1 + 4 = -2 + 4 = 2

x = 0

y = 2×0 + 4 = 4

x = 1

y = 2×1 + 4 = 2 + 4 = 6

so, the range is

{2, 4, 6}
