How To: Work with exponential growth functions in mathematics

Exponential functions are functions which contains terms which are integers raised to the power of variables. Note that the variables are not raised to the power of integers, but the integers are raised to the power of variables. Variables raised to the power of integers are called as polynomials and are a different class of functions. But exponential functions grow very fast than polynomials with the increase in the value of the variable. To understand the growth of these functions take a si...

How To: Sketch the graph of a piecewise function

This video teaches us to draw the graph of a piecewise function. This is shown using two examples. In the first example we have 'y' equal to 'x + 2' for x less than zero and '1 - x' for x greater than equal to zero. We plot two points on the function for x less than zero and do the same for the function with x greater than equal to zero. The graph for the first function is erased for x greater than equal to zero, and the same is done for the second function for x less than zero. Note that the...

How To: Graph the absolute value of a function

This video shows the method to plot the graph of the absolute value of a function. The video shows the example of the function of cube root of 'x'. The demonstrator first plots the graph of a cube root function. This is done by taking the reference point of positive one and positive eight. The graph is drawn for both negative and positive values of 'x'. After this the graph of absolute function is drawn by taking the absolute value of the cube root function. The resultant graph comes out to b...

How To: Clean fruit with vinegar

Keeping things clean is very important to prevent food born illnesses. Washing fruit is important. You can take care of many problems by just running them under water. You can use white vinegar and hydrogen peroxide to clean fruit. Start by spraying some white vinegar on the fruit and then a little hydrogen peroxide.

How To: Graph the greatest Integer or floor function

The video shows the explanation of greatest integer function. This video explains this with the help of graphs. The video first describes the basic greatest integer function. This means the greatest integer less than or equal to the number gave. The graph of this function is drawn. The video then shows the variations of this function. The first variation shows the function that replaces the 'x' coordinate with it subtracted by three. This shifts the graph to the right by three units. The seco...
