Question

Which logarithmic function has a y-intercept?

A. f(x) = log(x + 1) – 1

B. f(x) = log x + 1

C. f(x) = log(x –1) + 1

D. f(x) = log(x – 1) – 1

Answer 1

f(x) = log(x + 1) – 1

Explanation:

Its A on my computer however check to make sure it matches with yours because the answers get shuffled up sometimes.

Answer 2

Hello
the logarithmic function has a y-intercept is :
A. f(x) = log(x + 1) – 1
if x=0 : f(0) =log(0+1)-1 =log(1)-1=0-1=-1
the graph has a y-intercept in A(0 ; -1)
