QUESTIONS VERIFIED ANSWERS A+
◉ How do you find equation for lines on a piecewise function?.
Answer: use calculator
put in 2 coordinates then find the linear regression
◉ Which values are most of the time "critical" to include in order to
sketch the graph of most piecewise function?.
Answer: the starting and the end
◉ What are x-values that are graphed?.
Answer: domain
◉ What are y-values that are graphed?.
Answer: range
◉ What is the difference between [brackets] and (parenthesis)?.
Answer: [brackets] include the numbers on the end
(parenthesis) do not include the numbers on the end
ex:[8,7) means any number between 8(including 8) and 7(not including).
, ◉ Transformation.
Answer: change in the graph
ex: reflection
comparing to the original and seeing what changed/happened
◉ What shape do absolute value graphs make?.
Answer: V-shaped
◉ Why is infinity always in parenthesis instead of brackets?.
Answer: infinity is not a number, it is a concept.
◉ What are the 4 transformations of functions and explain them?.
Answer: 1) y=absolute value of x plus or minus k
*plus or minus k is OUTSIDE THE ABSOLUTE VALUE SIGN
*MOVES IT UP OR DOWN
2)y=k in front of the absolute value symbol
*When we multiply by a value in front of absolute value of x, we make
the graph wider or narrower
*If k is greater than 1, it is narrower
*If k is less than 1 (but greater than 0), it is wider
3)y=-k in front of the absolute value of x
*reflects the graph over the x axis, flips it
4)y=absolute value of x plus or minus k INSIDE THE ABSOLUTE
VALUE OF K
