In y = log ( x - a) + b
The ( x -a) part translates the graph left/right and the "b" translates it up/down
(x - a) translates the graph right by a units
( x + a) translates the graph left by a units
+ b translates the graph up by b units
- b translates the graph down by b units
Notice that it appears the the parent has been translated to the right by 3 units...
The thing that translates the parent to the right by 3 units must be " ( x - 3 ) "
So...it appears that the last answer is correct
To check this....note that (7,0) is on the graph...which means that
0 = log2 ( 7 - 3) - 2 must be true....so....
0 = log 2 ( 4) - 2 [ Note that log2 (4) = log 4 / log 2 = 2 ]
0 = 2 - 2
Which is true !!!!
Does this make sense ???
