Required
Solve the difference
The question you posted included the solution. However, the solution is incorrect;
The absolute difference is represented as:

In this case:


So, the distance is calculated as:

Open bracket



Steaks
s,t,k,s = 4 x 50 = 200
e,a = 2 x 15 = 30
200 + 30 = 230
1. One value of x for f(x)=-4 would be 0.
2. Should be 3.5 and -3.5 but I'm not sure
Answer: (0,0),(0,9),(9,0)
