Writing Quadratic Equations from Tables
Рет қаралды 79,133
2 жыл бұрынIn 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.

@thebielecmethod4884 11 ай бұрын
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.

How come you put 1/2 instead of just 1 for A?
@thebielecmethod4884 Жыл бұрын
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.

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.

what do I do if the x values do not go up by one?
@thebielecmethod4884 9 сағат бұрын
Usually the best way to go about this would be to create 3 separate equations with replacing the x and y’s in each of the 3 with the values provided. For example (2,8) when replaced with y=ax^2+bx+c, would be 8=a(2)^2+b(2)+c. This would then simplify to 8=4a+2b+c. Once you have the 3 different equations you will solve the system of 3 equations with 3 variables. This will give you the a,b and c values for the quadratic. I’d make a video but I’m on vacation until Saturday. If you still want a video, let me know and I’ll film it when I get back home. Thanks for the question and I hope this helps.

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.
