c. {545, 1045, 1545, 2045, 2545}

Step-by-step explanation:

Domain of a function is a set consisting of all the possible outcomes of the variable.

f (x) = 500 x+45 where x = 1,2,3,4,5

the possible outcomes for this function are:

f (1) = 500 (1) + 45 = 545

f (2) = 500 (2) + 45 = 1045

f (3) = 500 (3) + 45 = 1545

f (4) = 500 (4) + 45 = 2045

f (5) = 500 (5) + 45 = 2545
