The topic along with functions which we ought to deal with is combining functions. For the most part this means performing fundamental arithmetic (subtraction, addition, multiplication, & division) with functions. There is one new means of combing functions which we'll need to look at as well.
Let's begin with basic arithmetic of functions. Given two functions f(x) & g(x) we have the following notation & operations.
( f + g )( x) =f ( x ) + g ( x ) ( f - g )( x ) =f ( x ) - g ( x )
( fg ) ( x ) = f ( x ) g ( x ) (f /g) ( x ) = f ( x )/ g ( x )
Sometimes we will drop the ( x )part & just write down the following,
f + g = f ( x ) + g ( x ) f - g=f ( x ) - g ( x )
fg =f ( x ) g ( x ) f/g = f ( x ) /g ( x )
Note as well that we put x's in the parenthesis, however we will frequently put in numbers as well.
Solve following equations. (a) x 2 -100 = 0 (b) 25 y 2 - 3 = 0 Solution There actually isn't all that much to these problems. To use the square root property a

Preston wants to build a cement patio that will be 8 meters by 11 meters. It will cost $1.84 per square meter to build. What will be the total cost of the patio?
John can drive his car 15 miles on 2 gallons. How many gallons of gas will john need to drive 195 miles?
There is interesting relationship among the graph of function and its inverse. Here is the graph of the function & inverse from the first examples. We'll not deal along with the
The dashed line along with each of these parabolas is called the axis of symmetry. Every parabola contains an axis of symmetry and, as the graph illustrates, the graph to either s
To this instance in this chapter we've concentrated on solving out equations. Now it is time to switch gears a little & begin thinking regarding solving inequalities. Before we g
Solve (3x+ 1/ x + 4 ) ≥ 1. Solution The first thing that we have to do here is subtract 1 from both of sides and then get everything in a single rational expression. (3
