Explain what the vertical line test is and how it is used

Vertical Line Test. A test use to determine if a relation is a function. A relation is a function if there are no vertical lines that intersect the graph at more than one point.

The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input.

In 6 months the hair will grow 68.40 cm

Step-by-step explanation:

To understand that there are no miracles it is important to know that our hair cycle is not synchronized and that it is renewed continuously; that is, our scalp always has a majority of hair (approximately 80%) that are in a growth phase (anagen) and a minority, in the transition phase (catagen) and resting (telogen). The growth is a phase that lasts longer than the others (between 2 and 5 years, although it depends on age) and it depends on the final length of our hair; The longer it lasts, the more it will grow. "The average hair growth in the scalp is approximately 11.4 cm per month, an average of 0.4 mm per day. And it does so at a faster rate between 16 and 46 years, clearly decreasing from the 50.
