Had an interesting conversation after a test yesterday.
We teach parent functions ... and the current one is the absolute value function.
There were several questions on the test that stumped students but this one I just don't understand.
So we practice ... show me the absolute value parent function with your arms. Is the absolute value PARENT function ever negative ... no! What is it's equation ... yes ... always y = |x|. What if I reflect the graph ... what is the parent function? The parent function is always positive, it's always y =|x|.
Enter test question:
What is the parent function that represents the data below?
