Answer:

Vertical asymptotes can be found by solving the equation n(x) = 0 where n(x) is the denominator of the function ( note: this only applies if the numerator t(x) is not zero for the same x value). Find the asymptotes for the function . The graph has a vertical asymptote with the equation x = 1.

Additionally, how do you define Asymptotes? mpto?t/) of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity.

Regarding this, how do you find the horizontal asymptote of a function?

To find horizontal asymptotes:

If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).

If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Do all exponential functions have an asymptote?

Certain functions, such as exponential functions, always have a horizontal asymptote. A function of the form f(x) = a (bx) + c always has a horizontal asymptote at y = c.

Explanation:

the horizontal asymptote for y = 3^x is y=0

\displaystyle \lim_(x\to -\infty) 3^x=0\\ \lim_(x\to \infty) 3^x=\infty

The horizontal asymptote is
y=0. It's a left-side asymptote.
