2. Essential Questions
How do you use transformations to help graph absolute value functions?
Answer: you can use the values of a, h, and k in the form y = ±a|x – h| + k to determine how the parent function y = |x| has been transformed ( ± ⟹ + opens up/ - opens down, a ⟹ slope of sides, (h, k) ⟹ vertex).
