Writing Quadratic Equations from Tables
In this video I provide a table of values that would be created from a quadratic equation. I explain how to find all 3 needed terms to write out a quadratic equation. Important things to note is the way that I list out a, b, and c off to the side. This is so I can keep track of my findings and I work my way through the problem.

How would you find the Corresponding Y value and what’s the rule/formula for them?
@thebielecmethod4884
Жыл бұрын
Once you have the equation written out, you replace the x’s with whatever given value you have, then simplify the quadratic down to y= (whatever number you end with) Example: find corresponding y value for x=3 in y=2x^2+4x+3 You now have y=2(3)^2+4(3)+3 18+12+3 Y=33 If this doesn’t help I can make a video showing an example for you.

If the x-value on the tables increase by increments other than 1, can the same rule be applied for finding "a"?

We half the 2nd difference an^2+bn+c first four terms in a sequence of 1,2,3,4 produce a 2nd difference of 2a. By dividing by 2 we have now isolated the value of “a”. I will make a video explaining this and showing it as a proof.

In this scenario you need to set up 3 equations with variables typically being a, b, c. You then solve a system of 3 equations using elimination or substitution method. I can fill a video of this if you’d like me to post one this week for you.

Great question! Always take the second difference you find and cut it in half. For example: if your 2nd difference is 4 then your "a" would end up being 4/2, which is just 2. Let me know if this helps.
