Step-by-step explanation:
All three functions in the figure are parabolic and thus share the parent function
. They are horizontally dilated by some constant (unless they aren't) and can all be represented with
, where
is some constant.
Plug in point the line passes through to find that constant. For
, we can see the function clearly passes through (2,4):

Therefore, the function of
is 
Answer:
