Step-by-step solution

To determine whether it is possible to create an increasing and decreasing function using the two given points, we need to consider the concept of piecewise functions, which allow different behavior in different intervals.

Step 1: Recognize the nature of the problem. We have two points, which often prompts the consideration of either a linear or piecewise linear function.

Step 2: Analyze the end behavior. With the two points, we can begin by assuming a segment, a line, or a curve that connects them. To fulfill the request for both increasing and decreasing properties, the simplest approach involves using a piecewise-defined function. This can be achieved by defining one segment that is increasing and another that is decreasing, or vice versa.

Step 3: Implement a piecewise approach. Consider a three-point scenario by hypothetically placing a midpoint between the two existing points. This hypothetical point allows for an increase from the first point to the midpoint and a decrease from the midpoint to the second point. Such a function will satisfy the condition of having both increasing and decreasing segments.

Thus, it is indeed possible to define a piecewise function that achieves increasing behavior over one part and decreasing behavior over another by simply using the points or introducing an intermediate point to toggle between increasing and decreasing segments.

Therefore, the solution to the problem is Possible.

Possible

Key Points to Remember

Essential concepts to master this topic
  • Definition: Functions can have different behaviors on different intervals
  • Technique: Add intermediate point between given points to create segments
  • Check: Function increases then decreases (or vice versa) through all points ✓

Common Mistakes

Avoid these frequent errors
  • Thinking one function must be entirely increasing or decreasing
    Don't assume a function must have the same behavior everywhere = missing piecewise possibilities! A single function can increase on one interval and decrease on another. Always consider that functions can change direction by using intermediate points or curves.

FAQ

Everything you need to know about this question

Can a function really be both increasing AND decreasing?

+

Yes! A piecewise function can increase on one part and decrease on another. Think of a mountain peak - you go up one side and down the other, but it's still one continuous path.

Do I need to draw a straight line between the two points?

+

Not necessarily! You can create a curve or use multiple line segments. The key is making part of your function go up and part go down.

What's the easiest way to make this work?

+

Add an intermediate point between your two given points, either above or below the line connecting them. This creates two segments with different behaviors.

Does the function have to pass through both original points?

+

Yes! The problem asks you to use the given points, so your function must pass through both. But you can add extra points or curves between them.

What if the two points have the same y-value?

+

Even with points at the same height, you can still create increasing and decreasing sections by going up and then back down (or down then up) between them.
