Question
Does a logarithmic graph have a y intercept? Thanks
Hi Pam,
Like a lot of other questions about math, the answer is "it depends".
A basic graph, like y = log x or y = ln x, will not intersect the y-axis. But if its transformed by using a horizontal shifter, then it might:
y = ln(x+4) will have a y-int at (0, ln 4)
y = log(x+6) will have a y-int at (0, log 6), etc.
So, if a basic log graph is shifted to the left, or if its reflected across the y-axis, like y = ln(-x+4), it will then have a y-int.
Hope this helps.
