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...
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...
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'.
