Which function does the graph represent? f(x) = log(x + 3) + 1 f(x) = log(x + 1) + 3 f(x) = log(x + 1) – 3 f(x) = log(x – 3) + 1

It'd be a lot easier to help you if you'd share the answer graphs.

Just so that you know:

f(x) = log(x + 3) + 1 can be graphed as follows:

1.  Graph y = log x.  This function's domain is x>0.  It begins in Quadrant IV and ends in Quadrant I.  It intercepts the x-axis at (1,0).

2.  Now move the entire graph 1 unit to the left.  This gives you the graph of y = log (x+1).

3.  Now translate this entire graph up 3 units.  This gives you the graph of f(x) = log(x + 3) + 1.
