A function is the same: For example, you cannot put strawberries into a blender and get both a smoothie and chopped carrots.

Site Navigation Graphing Calculator: Among its uses are: By pressing you will get the Table SetUp screen. You will input four pieces of information in order to view a table.

TblStart is the x—value where you would like to start to table of values. DTbl is the increment by which you wish to count. Indpnt and Depend are asking you how much you would like the calculator to do for you.

If both are on Auto then the calculator will automatically fill in both the x—values the independent variable and the y—values the dependent variable in the table. By changing Indpnt to Ask and leaving Depend in Auto, you can input your own x—values and the calculator will automatically compute the y—values.

This option then eliminates the need for setting the starting point and increment since you will be choosing your own x—values. Otherwise the command will not register.

Setting Depend to Ask has no practical value. You cannot input a y—value and have the calculator return the corresponding x—values. You will most likely never need to set the Depend prompt to Ask.

A table of values is created for a function. So you must have something entered into y1.

You may have more functions entered, but an entry in y1 is a requirement for seeing a table. To see the table of values, press.

Using this table, you can see that: Pressing confirms the information in the table. First use the automatic setting and then input your own x—values.

You should be able to note that:Function Rules from Tables There are two ways to write a function rule for a table The first is through number sense.

This is the Harder of the two Function rules from tables When X=0, what does Y=?. • use words to a describe a rational function given a table, a graph, or a function rule • make a table of values for a rational function rule given words that describe a problem situation, a graph, or a function rule.

The first, flipping upside down, is found by taking the negative of the original function; that is, the rule for this transformation is –f (x). To see how this works, take a look at the graph of h (x) = x 2 + 2 x – 3. Function Machine Division: If you think the numbers are being divided by 2, simply enter ÷2.

While there are many ways to show division by 2, this machine is a bit lazy and will always opt for the easiest function. C - x intercepts of the graph of a quadratic function The x intercepts of the graph of a quadratic function f given by f(x) = a x 2 + b x + c are the real solutions, if they exist, of the quadratic equation a x 2 + b x + c = 0 The above equation has two real solutions and therefore the graph has x intercepts when the discriminant D = b 2 - 4 a c is positive.

Example 1: Write a function Rule for each table x 3 2 4 5 6 4 6 8 10 12 y x 8 10 12 14 16 1 3 5 7 9 y. Unit 4 Section 6 Writing a Function benjaminpohle.comok February 17, Unit 4 Section 6 Writing a Function benjaminpohle.comok Subject: SMART Board Interactive Whiteboard Notes.
