Answer:
If a one-to-one function is not continuous, it is sometimes increasing or decreasing. If a one-one function is continuous, it is always increasing or always decreasing.
For example, if
This function is one-to-one and it is not always increasing or decreasing.
Step-by-step explanation:
A statement that are one-to-one functions either always increasing or always decreasing is given.
It is required to explain the given condition.
To explain the given condition, consider a continuous and a not continuous function then explain about the one-to-one function.
If a one-to-one function is not continuous, it is sometimes increasing or decreasing.
For example, if
This function is one-to-one and it is not always increasing or decreasing.
If a one-one function is continuous, it is always increasing or always decreasing.
For example, if f(x)=x-3. It is a continuous function and it reaches a minimum value at some values of x and it then keeps increasing.
There will be the same output value for different input values. It does not pass the horizontal line test and so it is not a one-to-one function.

Answer:
$600
Step-by-step explanation:
Simple Interest Rate: A = P(1 + RT)
A Total Value
P Principle
R Rate
T Time
__________________________________________________________
<h2>Step 1: Insert Values </h2><h2> </h2>Let's plug the info we have into the formula:
A = 4000(1 + 0.05(3))
A = 4000 + 4000(0.15)
A = 4000 + 600
A = 4600
__________________________________________________________
<h2>Step 2: Finding the Interest</h2><h2 />So the total value she ends up with $4600, but we want to find the extra value, or interest, she has to pay.
To find this we subtract the principle from the new value:
4600 - 4000 = 600
Liz has to pay $600.
