WHEN LOGARITHMIC FUNCTIONS ARE GRAPHED WHICH TRANSFORMATION WILL RESULT IN A Y INTERCEPT?

Question

Please explain if you can.

Answer 1

y= lnx has no y intercept

shift the function to the left

y=ln(x - b) where b is any constant

for example b= -1

then y=ln(x+1)

when x=0, y=ln(0+1) =ln(1) = 0, the y intercept =0 or the origin, the point (0,0) is where the function intersects the y axis.
