Well I think I should go over the answers and how we got that but since my classmates are so smart. I don't think it's necessary and considering the fact that the quiz was so straight forward. But since there seemed to have been some confusion near the end of class I will try to clarify things. Since it was the quiz that confused some people, I will not reference to the quiz. Hopefully you will be able to understand after my explanations.
Vertical stretches/ compressions: A vertical stretch/ compression is represented by the form of
Example one: Stretch x^2 by a factor of 3.
All the y-values are now higher. We just stretched the graph vertically up.
Horizontal Stretches/ Compressions: A horizontal stretch is represented by the form of
Vertical Shift; A vertical shift is represented by the form of
y= f(x) + d
Where d is the upward or down shift.
Example three: Shift x^2 up by 1 unit.
Horizontal Shift; A horizontal shift is represented by the form of
y= f(x - c)
Where c is the left or right shift.
Example four. Shift x^2 right 1 unit
All Together Now
Well that was basically what the quiz was on, translations. And as you can see near the middle of the post I came across some format problems that I just can't seem to fix ): I hope this will help you understand the mistakes that you might have made on the quiz. And if you still want me to go over the quiz I will if needed.
