What does a # / Hashtag / pound sign actually mean in Social Media? The pound sign or hashtag is visually represented by the symbol â#â, and by placing the symbol in front of a word (or series of words) on a social network, it will turn that word into a metadata tag.
Note: You can't go through algebra without seeing quadratic functions. The graphs of quadratic functions are parabolas; they tend to look like a smile or a frown. In this tutorial, get introduced to quadratic functions, look at their graphs, and see some examples of quadratic functions!ou can't go through algebra without seeing quadratic functions.

Do you know what the graph of this equation looks like? It looks like a line! Thus, exponential functions, when plotted on the log-linear scale, look like lines. We call this type of plot log-linear because we are plotting the logarithm of the dependent variable (log (y)) against the independent variable (x).Why use the log-linear scale? Plotting on the log-linear scale is an easy way to determine if a quantity is growing exponentially because the graph should look like a line.Assuming exponential growth, the slope of the line, m, is given by the logarithm of the base of the exponential function, log (a).e call this type of plot log-linear because we are plotting the logarithm of the dependent variable (log (y)) against the independent variable (x).
