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...
Quadratic Function Models Consider the following table of the number of Americans that are over 100 in various years. Year Number (in 1000's) 1994 50 1996 56 1998 65 2000 75 2002 94 2004 110 How many would you predict would be over 100 in 2008? Let's plot the data in our calculator...
