A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function
Answer:
Step-by-step explanation:
1. Domain: {-5, -3, 0, 4}
Range: {-2, -1, 7}
Function? No
2. Domain: {-6, -3, 0, 1, 4}
Range: {-5, -2, 5, 7}
Function: Yes
3. Domain: {-3, -2, -1}
Range: {-9, -1, -6)
Function: No
Profit = revenue - expenses
12000 = 12x - (7.50x + 10,000)
12,000 = 12x - 7.50x - 10,000
12,000 + 10,000 = 4.5x
22,000 = 4.5x
22,000 / 4.5 = x
4888.88 rounds to 4889 = x......4889 baseballs
