Question

Hayden purchases a new kayak. The kayak's value decreases by 25% each year. The following graph could be used to represent the kayak's value y after x years.

a graph of an exponential function decreasing from the left passing through the points 0 comma 180 and 8 comma 0

Based on the graph of the function and the context of the problem, what is the domain and its meaning?

x ≥ 0; The number of years Hayden owns the kayak is always greater than or equal to 0.
0 ≤ x ≤ 8; The number of years Hayden's kayak has a value is greater than or equal to 0 but less than or equal to 8.
0 ≤ x ≤ 180; Hayden's kayak will always be greater than or equal to $0 and less than or equal to $180.
ℝ; Hayden's kayak will always have a value.

Answer 1

0 ≤ x ≤ 10; The number of years Hayden's kayak has a value is greater than or equal to 0 but less than or equal to 10.

Answer 2

Answer: 0 ≤ x ≤ 8; The number of years Hayden's kayak has a value is greater than or equal to 0 but less than or equal to 8.

This is the answer other one was wrong I put this answer on the test got an 100%.
