You will need to multiply 2.25 by 375.5 which will then give you 844.87 but if we round it the answer will be 844.9
F(x)=[x]
The vertex of this function is (0,0);
f(x)=[x-4] The vertex of this function is now (4,0)
f(x)=[x-4] -2 The vertex of this function is now (4,-2)
Answer: f(x)=[x-4]-2
40,619 would be the answer.
