- Function for value- V(t) = 2000*0.86^t
<u>The second laptop</u>
- Initial value- $1200
- Value loss - 11% every year
- Function- V(t) = 1200*0.89^t
b)
Monthly percent decrease

Step-by-step explanation:
The graph is of a function (one output for every input) that also passes the horizontal line test (one input for every output). Hence it is one-to-one.
For a <em>function</em>, the key for it being one-to-one is that it pass the horizontal line test.
