How do you find the asymptote of a logarithmic equation?
Last Updated: 29th May, 2020
- When graphed, the logarithmic function is similar in shape to the square root function, but with a vertical asymptote as x approaches 0 from the right.
- The point (1,0) is on the graph of all logarithmic functions of the form y=logbx y = l o g b x , where b is a positive real number.

Thereof, how do you find the equation of the horizontal asymptote?
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.
Furthermore, what is the property of log? Logarithm of a Product Remember that the properties of exponents and logarithms are very similar. With exponents, to multiply two numbers with the same base, you add the exponents. With logarithms, the logarithm of a product is the sum of the logarithms.
In respect to this, how do you find the asymptotes of an LN graph?
Find the vertical asymptote of the graph of f(x) = ln(2x + 8). Solution. Since f is a logarithmic function, its graph will have a vertical asymptote where its argument, 2x + 8, is equal to zero: 2x +8=0 2x = −8 x = −4 Thus, the graph will have a vertical asymptote at x = −4.

Finding Horizontal Asymptotes of Rational Functions
- If both polynomials are the same degree, divide the coefficients of the highest degree terms.
- If the polynomial in the numerator is a lower degree than the denominator, the x-axis (y = 0) is the horizontal asymptote.
