How do i find vertical asymptotes using an exponential function? (f(x) = ab^(x-h) + k)

i know that horizontal asymptotes are y = k, but i don't know how to find the vertical

asymptote: a line that a graph of a function approaches without touching.

Having a vertical asymptote (basically) means there is a non-removable discontinuity for some value of x. The given f(x) will be defined for all values of x, so it's continuous and thus has no vertical asymptotes.

(3x-8) or (3x+8)

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
