The answer for it is 4 at x=-5. You need to take a derivative of you function and set f'(x)=0, then you find critical points. Set those x values into f(x) and take the lowest value.

Answer:
The vehicle can travel 12 miles per gallon of gas.
Step-by-step explanation:
- The number of gallons used by a vehicle = 1 1/8 gallons
i.e.
gallons
- The number of miles traveled by a vehicle = 13 1/2 miles
i.e.
miles
Thus,
Total Gallons =9/8 gallons
Total Distance in miles = 27/2 miles
Hence:
Unit Rate = [27/2 miles] / [9/8 gallons]
= 12 miles per gallons ∵
Therefore, the vehicle can travel 12 miles per gallon of gas.
Answer:
A 2sqrt(7)
Step-by-step explanation:
Use similar triangles and ratios of lengths of corresponding sides.
2/x = x/14
x^2 = 28
x = 2sqrt(7)
