Step-by-step explanation:
Car travelling to the east is at 104 miles per hour and the car travelling to the west is moving at 114 miles per hour
Start from the parent function 
In the first case, you are computing

In the second case, you are computing
, you translate the function horizontally,
units left if
and
units right if
.
On the other hand, when you transform
, you translate the function vertically,
units up if
and
units down if
.
So, the first function is the "original" parabola
, translated
units right and
units up. Likewise, the second function is the "original" parabola
, translated
units left and
units down.
So, the transformation from
to
is: go
units to the left and
units down
