Equation: 4 + 4x + x²
Maxima: No maximum value from said equation
Minima: x = -2 since that is the only critical point in the equation

Answer:
- boat: 15 mph
- current: 5 mph
Step-by-step explanation:
The relation between time, speed, and distance is ...
speed = distance/time
__
The speed downstream is ...
downstream speed = (100 mi)/(5 h) = 20 mi/h
The speed upstream is ...
upstream speed = (100 mi)/(10 h) = 10 mi/h
The boat's speed in still water is the average of these:
boat speed = ((downstream speed) + (upstream speed))/2 = (20 +10)/2 mi/h
boat speed = 15 mi/h
__
The speed of the current is the difference between the travel speed and the boat speed:
current speed = downstream speed - boat speed
= (20 mi/h) - (15 mi/h)
current speed = 5 mi/h
