Which of the following describes the following graph? A. neither a function nor a relation
B. function only
C. relation only
D. both a function and a relation

Sorry but theres no graph :(

h(x) = -1200x^2 + 1950x + 4950

Work Shown:

f(x) = revenue from the north

f(x) = -750x^2 + 1500x + 2250

g(x) = revenue from the south

g(x) = -450x^2 + 450x + 2700

h(x) = total revenue, ie add the two revenues

h(x) = f(x) + g(x)

h(x) = (-750x^2+1500x+2250)+(-450x^2+450x+2700)

h(x) = -1200x^2 + 1950x + 4950
