Question

The fuel tank of a certain airplane can hold up to 300 gallons of fuel. Let Wbe the total weight(in pounds) Let F be the total amount of fuel in this tank ( in gallons) Suppose that W = 6F +4000 gives W as a function of F

Answer 1

Range of weight = [4,000 , 5,800]

Explanation:

Given:

Function W = 6F +4000

Full amount of fuel = 300 gallons

No amount of fuel = 0 gallons

Find:

Range of weight

Computation:

Domain : amount of fuel = [0 , 300]

If F = 0

W = 6F + 4,000

W = 6(0) + 4,000

W = 4,000

If F = 300

W = 6F + 4,000

W = 6(300) + 4,000

W = 5,800

Range of weight = [4,000 , 5,800]
