Formula y = a(x-h)^2 + k
Equation: 𝑦 = 2(𝑥−4)^2 + 2
Equation: y = x^2
The “A” in the formula determines the width of the parabola. Also, if “A” is negative, it will open downwards instead of upwards like my equation. “H” and “K” will determine the vertex of the parabola and vertex’s position. The “H” determines which side the vertex will be on the graph, if the number is negative, it will shift right if its positive it will shift left. The “K” will determine if the vertex will be below or above the 0. Therefore, if the number is positive, it will be above and if its negative it will be below. In conclusion, my parabola is different compared to the other one because both equations don’t have the same vertex and “A“.
Self-Assessment
- I used the same mathematical ideas by a graph, and equation, and using my words.
- A few vocabularies I used to demonstrate my understanding were parabola and vertex.
- I used a graph and made it big enough where it is shown clearly. I also wrote both of the equations and highlighted it to show which one it is on the graph. I highlighted A, H, and K in the formula and my equation to help share the information clearly.
