Transforming Parabola

y=(1/3)(x+1)^(2)-3

The vertex for my parabola is (-1, -3)

The vertex for the parent function is (0, 0)

The “a”, “h”, and “k” values are used to transform the parent function. The a value is what determines if the parabola is stretched, compressed, or flipped. If the “a” value is smaller than one or greater then negative one, then the parent function is stretched because the parabola grows at a slower rate. on contrary, if the “a” value is greater than one or less than negative one, the parabola will compress because the parent function will grow at a faster rate. The “h” value is what determines x value of the parabola. The “h” value shifts the parabola left or right. If the “h” value is negative then the parabola will shift left and if the value is positive, the parabola shifts right. The last value is “k” and this helps determine the y value of the parabola. The “h” value will shift the parabola up or down depending on if it is negative or positive. Positive “h” value will move it up, and negative will move it down.

Since the “a” value on my function is less than one and greater than negative one, my parabola got stretched. The “h” value is a positive, so my parabola was shifted to the left by one unit. The “k” value of my parabola is negative three so my parabola shifted down three. This is how the “a”, “h”, and “k” value transformed and shifted my parabola.

Self- Assesment

  1. How did you represent the same mathematical idea in multiple ways in this assignment?
  2. State how the relevant mathematical vocabulary words you used to demonstrate your understanding?
  3. How did you use formatting to share this information in a clear and orgainized way?
  1. I represented the same mathematical idea is multiple ways by showing both the graph for visual learners and in a form of a paragraph for the people who need and learn better from an explanation.
  2. I used words such as, streched or compressed to show the parabola stretching and compressing. I also used the vocab such as shifting or transforming to describe the changes in the parabola.
  3. I used formatting from desmos to show a clear and organized graph. I also used simple and bold titles in Edublogs to be clear of what I will be disscussing.

By doing…in the classroom, I make a positive difference to my peers.

By sharing positive feedback and ideas while we are doing group work. I try to help my peers the best I can and discuss with them the problems we have in front of us. I try to talk with all my peers to get to know each of them. By doing these things, I can make a positive difference to my peers.

Some of the ways I work to build and maintain relationship are not to be negative towards my peers. I stay positive towards their ideas and their opinion. I always come to the group with a positive attitude. By maintaining a positive relationship between me and my peers it makes it easier to talk and collaborate with them for school work.

When I need to boost my mood or re-focus, I like to take a break and come back to the question, task, or challenge. I think this gives my a fresh and new perspective of the problem and I can think better after taking some time to stop thinking so hard on that one question.
