Question

Hello can you please help me for those questions, I have solved them but I am concerning about my answers if they are correct or no?

Find the vertical asymptote, domain and key point of each of the following logarithmic functions.

1) F(X)=Log₂(x+5)-3

2)F(X)=Log₅(x-3)+1

3)F(x)=Log₃(x-4)+2

4)F(X)=3Log₂(x-1)+2

5)F(X)=1/2Log4(x-6)-5

6)F(X)=-4Log₂(x-2)

Answer 1

1) Vertical asymptote x = - 5

2) Vertical asymptote x = 3

3) Vertical asymptote x = 4

4) Vertical asymptote x = 1

5) Vertical asymptote x = 6

6)Vertical asymptote x = 2
