A quadratic function can always be factorized, but the factorization process may be difficult if the zeroes of the expression are non-integer real numbers or non-real numbers. In such cases, we can use the quadratic formula to determine the zeroes of the expression. The general form of a qu...
Example 1: Using a Table of Values to Graph Quadratic Functions Notice that after graphing the function, you can identify the vertex as (3,-4) and the zeros as (1,0) and (5,0). So, it's pretty easy to graph a quadratic function using a table of values, right? It's just a ma...
That is, in a quadratic function, the highest power of x (or the variable of interest) is 2. Put more formally, we can write a quadratic function like this: f(x)=ax2+bx+c where a≠0, and b and c are real numbers. Notice that if a is zero, then the function is no longer ...

In the previous lesson, you graphed quadratic functions using a table of values. In that lesson, I gave you the x values within the table of values. How would you know which x values to choose if you were graphing a quadratic function on your own? How would you be sure that you chose...

It can be shown that the bending moment M of this type of cantilever is a function of the distance x measured from the fixed end of the beam, thus M = f(x). The defining equation for the function is: M=f(x)=Wx22−5WLx8+WL28 where W is the distributed load in newtons per ...
