First find g(0). g(0) is -1. Now find f(-1). f(-1) will be 1. So your answer is C.
Answer:
B(-2,-6)
Step-by-step explanation:
The midpoint of AB is M, then A(8,4), M(3,-1)
So we can find:

then B(-2,-6), hope that useful.
Answer: 9
Step-by-step explanation: 31-4=27
Answer:
At ; I = 3, P is at maximum
Step-by-step explanation:
P ( I ) = ![[ \frac{80 I}{I^2 + I + g } ]](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7B80%20I%7D%7BI%5E2%20%2B%20I%20%2B%20g%20%7D%20%5D)
at I = 3
P" ( I ) < 0
therefore at I = 3 the value of P( I ) is at maximum
