Using each value of the domain in the function to find each value of the range.
Let c = 0, 15, 50, and 62 (one at a time)
c = 0
p = 6c - 300 = 6(0) - 300 = -300
c = 15
p = 6c - 300 = 6(15) - 300 = 90 - 300 = -210
c = 50
p = 6c - 300 = 6(50) - 300 = 300 - 300 = 0
c = 62
6(62) - 300 = 372 - 300 = 72
The range is {-300, -210, 0, 72}
