Determine the domain of the following function:
The function represents the weight of a person over a period of 3 years.
Logically, a person's weight is something that fluctuates.
In one week, a person's weight can increase, but in the following week, it can decrease.
Therefore, the domain that suits this function is - partly increasing and partly decreasing.
Partly increasing and partly decreasing.
Is the function in the graph decreasing?
Domain is the set of all possible input values (x-values). Function behavior describes whether the output increases, decreases, or does both. Don't mix them up!
For a 3-year period, the domain would be [0, 3] if starting from year 0, or whatever time interval makes sense for the context.
In real life, a person's weight naturally goes up and down due to diet, exercise, health, and daily variations. This makes the function partly increasing and partly decreasing.
Yes! Most real-world functions have different behaviors over different intervals. A weight function might increase during some months and decrease during others.
Read carefully! Sometimes questions have mismatched titles and answer choices. Focus on what the answer choices are actually asking for, even if the title says something else.
Think about the real-world context! Weight naturally fluctuates, temperatures rise and fall, and populations grow then decline. Use logical reasoning about the situation.
