Watch the video on “Seven Elementary Functions and Their Graphs” and answer:

• Which is the “parent” of all linear functions?
• Which is the “parent” of all the quadratic functions?
• Which is the “reciprocal” function?
• Name and describe the 7 elementary functions.
• Which of these functions don’t have negative values of y? (And explain why they don’t have negative values of y): “identity function”, “absolute value function”, “squaring function”, “cubing function” and “square root function”.
