How do you find the asymptotes for #4^(x-5)-5#?

Answer 1

#(infty, infty)# and #(-infty, -5)#

#4 ^ (infty - 5) - 5 rightarrow 4^infty rightarrow infty#
#4 ^ (-infty - 5) - 5 rightarrow 1/(4 ^ infty) - 5 rightarrow -5#

Answer 2

To find the asymptotes of the function (f(x) = 4^{x-5} - 5), we need to consider both horizontal and vertical asymptotes.

  1. Vertical Asymptotes: Vertical asymptotes occur when the function approaches positive or negative infinity as (x) approaches certain values. However, for the given function, there are no vertical asymptotes since it is defined for all real values of (x).

  2. Horizontal Asymptotes: Horizontal asymptotes occur when (x) approaches positive or negative infinity. To find horizontal asymptotes, we analyze the behavior of the function as (x) approaches infinity and negative infinity.

As (x) approaches positive infinity ((x \to \infty)), (4^{x-5}) grows without bound. Therefore, the term (4^{x-5}) dominates the function, and (f(x)) behaves like (4^{x-5}). Since the constant term "-5" becomes negligible compared to the rapidly growing exponential term, the horizontal asymptote is at (y = -5).

As (x) approaches negative infinity ((x \to -\infty)), the exponential term (4^{x-5}) approaches (0). Thus, the horizontal asymptote in this case is also at (y = -5).

Therefore, the horizontal asymptote for (f(x) = 4^{x-5} - 5) is (y = -5), and there are no vertical asymptotes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
