Question

The directions on a turkey tell you to cook the turkey 20 minutes per pound.

Part A: Write a function in function notation for this situation where X is the number of pounds.
Part B: Describe the domain of this function. Assume turkeys can weigh up to 30 pounds.
Part C: Graph this function and state the range.
Part D: Use this graph to determine the cooking time for an 18 pound turkey.

Answer 1

Explanation:

Let y be the time required to cook the turkey, and x the number of pounds of the turkey.

The time required, x, is equal to the turkey's weight (in lbs) times 20 min/lb.

y = 20(min/lb)x

The domain of this function is 0 - 30 pounds.

The cook time for an 18 lb turkey is y = (20min/lb)*(18 lb) = 360 min
