Question

Need help with this math question

which logarithmic function has a y-intercept

f(x)=log(x+1)-1
f(x)=log x+1
f(x)=log(x-1)+1
f(x)=log(x-1)-1

Answer 1

the one shifted the left at least somewhat, because the parent function only tends towards the y-axis but never reaches it.

Answer 2

(can be shifted to the left in order to have a y-intercept,
--> REGARDLESS of the vertical shift)

Answer 3
