Skin tags that have changed color or bleed may require your doctor's evaluation and reassurance. Rarely, thrombosed skin tags may be a sign of another condition and need to be biopsied.
The x-axis and y-axis are two lines that create the coordinate plane. The x-axis is a horizontal line and the y-axis is a vertical line. I'm sure you've heard that a million times, but it might hard for you to remember which one is which. Here is a little trick to help you remember...
On solving, we get 2. So, the horizontal asymptote for the horizontal line is y = 2. Vertical Asymptote: The equation of the vertical line is given by x = t. Given equation is a vertical asymptote of a graph which has a function y = f (t). This function is applicable, when one of the given condition is true.
