    f (-4) = 2 (-4) + 2 = -8+2=-6

    f (-2) = 2 (-2) + 2 = - 4+2=-2

    f (1) = 2 (1) + 2 = 4

    f (3) = 2 (3) + 2 = 8

    Step-by-step explanation:

    Actually the domain is the value of the x that are allowed. Or, other words you can assume that it is the set of input values that are allowed. And through it we find the set of output values, or what we know as a range. So 6,-2, 4 and 8 here forms the range.
