    x and y intercepts of logarithmic equation

    How would I solve the x and y intercepts of this and find its horizontal asymptotes:

    h(x)=log_2(x-1)+2

    You should essentially be asking:

    x-intercept ==> For what x, is h(x) = 0 ?

    y-intercept ==> If x = 0, what is h(x)?

    Can you try now?

    x-intercept: Solve 0 = \log_2(x - 1) + 2. Is there a real solution?

    y-intercept: Substitute x = 0. Is there a real solution?

    Horizontal asymptote: None.

    Vertical asymptote: Solve x - 1 = 0 ......
