Find the range of the function y=-x+3
when the domain is (-2,0, 2, 4).

Range: {5, 3, 1, -1}  or in numerical order: {-1, 1, 3, 5}

Step-by-step explanation:

The range is the set of output or y-values for every input (or x-values). Given the following domain: {-2, 0, 2, 4} and the given linear function, y = -x + 3:

Domain (x)            Range (y)

   -2                 y = -(-2) + 3 = 2 + 3  = 5

    0                 y = - (0) + 3 = 0 + 3  = 3

    2                 y = -(2) + 3  = -2 + 3  = 1

    4                 y = -(4) + 3  = - 4 + 3 = -1
