Determining if a Function is Linear, Quadratic, or Exponential from a Table

If we are given a table of functions, how do we determine if the functions are linear, quadratic, or exponential?
Edit - When going through the examples in this video, you'll hear me using the phrases "Change in y" or "Change in change of y (I also say change of y is delta y)". The terms you'll probably see in class are usually "First difference" and "Second difference." I wanted to write that as I don't think any teachers use "change in the change" unless they're explaining what "second difference" means. Maybe your teacher uses a different phrase (please post below, that'd be helpful for others!) but I wanted to update this with what you'll most likely see in class so you're not like "what in the world is change in change my teacher's never used that?!" 😂 Hope that helps! 🙌

    The lesson in the modules I received was not clear enough to understand so I don't understand the lesson and other videos on youtube about this lesson are not that clear until I cross into this video lesson, it is easily and clearly explained. There are also laughs along with the lesson which is I like. It really helps me a lot, thank you very much❤️❤️

    what happens if there are negative values and the differences become negative do i take the negative into account or do i just state the difference without adding a negative?

  • @TopTierMath

    @TopTierMath

    2 жыл бұрын

    Great question! If the differences are negative, make sure to keep them negative. If you make them positive, (which seems reasonable, right?) it'll change the whole problem you're working on (and give you the wrong answer) because we need to see what the pattern is for the first and/or second difference and changing a negative to a positive will alter the pattern you get. I hope that helps!

    i don't get the second problem how is it linear

  • @TopTierMath

    @TopTierMath

    Жыл бұрын

    Hey Dyllian! I'm so sorry for the uber late response, but in case you were still wondering here's why: Linear just means a constant rate of change. So when we're dealing with coordinates like these problems, the following must be true if it's linear: Pick any two coordinates aka (x,y) points and find the change in y divided by change in x (that's where y2-y1/x2-x1 comes from). You'll get some fraction. You should get that same exact fraction (you may need to simplify) for ANY two coordinates that you pick and do the same to (change in y divided by change in x). If you get a different value for even one pair (again, remember to simplify the fraction if needed), then that set of coordinate points does not represent a linear function. Because we got the same fraction for all pairs of coordinates on problem 2, that represents a linear function. Let me know if that helps!
