Chemistry 12 Core Competency

I can take on roles and responsibilities in a group: I do my share. The key to a successful lab is clear communication with peers. Throughout the lab, I was able to take on the role in charge of heating and watching the precipitate dissolve. I did my share and allowed my partner to do his. Furthermore, we had clear communication on our roles and responsibilities. This allowed us to have a quick and thorough lab that developed our skills in determining the solubility constant.

Transforming Parabolas

Graph A: Quadratic parent function 𝑓(π‘₯)=X^2

Graph B: Shifted up 𝑓(π‘₯)= (x-6)^2+2

Graph C: Opens up and is wider 𝑓(π‘₯)= 1/3 (x+7)^2 -5

Graph D: Opens down and is more narrow 𝑓(π‘₯)=-10(x-5)^2

Graph E: Shifted down 𝑓(π‘₯)=-(x+1)^2-1

A, H, and K all play significant rolls in where the parabola is and the shape that it has. The A coefficient determines the direction and width of the parabola. If A is positive the parabola opens upwards; if A is negative it opens downwards. A affects the width of the parabola; the larger the value the narrower the parabolas is. Graph C has a width larger than the parent function which means the coefficient of A is between 0-1. The value of H moves the parabolas left or right on the graph. It represents the x-coordinate of the vertex. Thus, meaning if H is positive the parabola is shifted to the right, and if it is negative it is shifted to the left. Graph D represents a positive value of H, because it has shifted to the right of the parent function. The value of K shifts the parabola up or down. It corresponds with the y-coordinate of the vertex. A positive K moves the parabola upward and a negative K moves it downward.

Self Assessment

  1. In this assignment I was able to approach the concept from different angles to deepen my understanding. I used algebraic explanations, in the paragraph explain the significance of A, H, and K. Furthermore, I created multiple parabolas to showcase the geometric transformations of the parabolas. Taking the information that was given in text I created functions that better showcase the purpose of A, H, and K.

2. Throughout this assignment I used mathematical vocabulary such as, vertex, coefficient, shift, function, positive, negative, and coordinate. Using the mathematical vocabulary I was able to create a clear and understandable paragraph that explains the importance of A, H, and K.

3. I was able to format this assignment in an organized way to make it clear and easy to read. Furthermore, I clearly labeled and coloured coded my graphs to make it easier to follow. Also, I used headers and bolding writing to separate unlike text.

Math Self Assessment

An example of something I spent lots of time learning about is Trig. Trigonometry at first was very challenging, however as I got help from peers and Ms. Rands I understood the math concept and was able to overcome the challenge.

To celebrate an accomplishment such as getting 100% on my trigonometry test I do not celebrate it much. I celebrate it for 5 minutes however after those 5 minutes, I resume my day and focus on other things. It lifts my mood and also makes me more confident but I do not get out of my way to celebrate it.

When I am sad, angry, or frustrated I listen to music. It helps me calm down which in return allows me to be productive.

Some of the ways I work to build and maintain relationships are by simply talking to them. I talk to the about whatever one wants. I also maintain relationships by hanging out with the person and doing activities that make everyone laugh.
