Question

What is the parent function of the graph?

y = |x|

y = |x| + 4

y = |x – 4|

y = |x| – 4

Answer 1

Answer: Choice A) y = |x|

The graph in blue is y = |x|-4 which is the result of shifting y = |x| four units down. The parent graph has the vertex at (0,0).

Answer 2

It would be D. Because K represents the up or down part of the graph. The formula for parents function is (x+ or -h) +or-k. It does not show h being applied to the main point.
