How do you graph #y=lnx+3#?

Explanation:

It's best to always have in mind what the reference function looks like (#y = lnx# in this case)

We know that the function #y = lnx# has an #x#-intercept at #x = 1# or (#1,0#) so we can use that as a reference point.

Now, the function #y = lnx +3# asks to move all values up 3 units so if we take that reference point I mentioned earlier and move it up 3 units you'll get the point #(1,3)#

In essence, when you graph #y = lnx +3# all you're really doing is moving the entire graph up 3 units so its the same graph #y = lnx# just moved up 3 units.

Hope you understand this topic a little better now!
