Hello,
The second derivative indicates the rate of variation of the first derivative. Each point where the second derivative vanishes (has value 0) is an inflexion point of the curve.

How about using you calculator to graph that function? that is how you learn things. It will be my pleasure to help you learn how to graph functions.

### How do I graph x<-3 on the calculator?

First you must use a graphing calculator.
Most graphing calculators graph functions, i.e. relations of the form y=f(x).
Some graphing calculators are able to graph equations (not necessarily functions). On one of these calculators your draw the vertical line x=-3, then you shade to the left of the point x=-3. That gives you the real line from infinity up to but not including x=-3.
Generally, people do not need calculators to find the solutions to inequalities in just one variable.

### How do I graph y=4/5x -1 (where 4/5 is 4 over 5, not 4 divided by 5)

Before trying to graph anything lift the ambiguity from the expression. That is what parentheses are for. Besides, there is no difference between 4 over 5 and 4 divided by 5. They mean the same thing.
Look at the screen capture and see how many possible interpretations you can have for your expression.

Use parentheses to enforce your intention.
4/5X-1 gives the first expression on display.
4/(5X-1) gives the second expression
4/5X^-1 gives the third.

To graph, press the MENU key then use arrows to focuss on GRAPH. Press ENTER/EXE
In the Y= editor type in the intended expression after Y1= and press EXE.
Press DRAW.

y=x2-4x+3
here,a=1(coefficient of x2)
b=-4(coefficient of x)
c=3(the constant term)
as this is a quadratic equation this will have two solutions
solution 1=(-b+square root of(b2-4ac))/2a
=(-(-4)+square root of(16-4*a*c)/2*1
=3
solution 2=(-b-square root of(b2-4ac))/2a
=1

### Whenever i try the graph on my TI-83 Plus the ERR:INVALID DIM 1:QUIT comes up and ive checked the STAT PLOT and i have Plot 1 set as ON.

You have to turn all statistical plots OFF before you draw function graphs. Press [2nd][Y=] to open the statistical plot configuration screen. Press [4:PlotsOFF] and then [ENTER]. When calculator answers DONE you are ready to draw function plots.

### How do i input the equation f(x)= x^3 -3x+2 (-2,2). I need to graph and fine the local maximum and minimum

I am puzzled by the (-2,2) after the equation. I suspect it is the coordinates of some point. But I won't push the matter further, and I will just ignore that info. I am no mind reader.
1. Turn calculator ON.
2. If you do not see icons, press Menu.
3. Use navigational arrows to highlight [GRAPH] and press [EXE]
4. Type the function.
5. Use the [X.T,theta] key below [ALPHA] to type the X variable or the [ALPHA][+]. In general you should use the [X,T,theta] because is context sensitive: If you draw parametric or polar graphs, pressing that key gives you the right variable (T, or theta)
6. Use the caret [^] 3 to raise X to the third power and complete the function. and press [EXE]
7. At the bottom of the screen you see some tabs.
8. Press [F3:Type] and you will see all types of graphs you can draw. But since you want Y=, press [EXIT] to return to Y=editor
9. Press the Function key to above which you see [DRAW]
10. Adjust the Window dimensions if necessary
Finding the min and max
• While the graph is still displayed press [SHIFT][F5:G-Solve].You see all the possible calculationsF1:root, F2:Max,F3:Min,F4:YiCPT (y_intercept),F5:Isct (intersection) F6:=> to show the others, among which is the F3:integral.
• Press F3:min and hold your breath.
• After a while you get your minimun. Be patient, even if the small square at the top right disappears.
• Once you get the minimum, press [SHIFT][F5-G-Solve] and repeat for the maximum.

### I dont know how to graph

Hello,
Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.
An entry screen appears where you enter the functions you want to graph.
On the first line you have Y1= . After the equal sign enter 2[x] [X, theta,T] + 1. When finished press [F6: Draw] Your graph appears on the screen. If you see the axes, but no graph, press [Shift][V-Window] and press [F3:Std] then [SHIFT][QUIT] will take you back to the screen where you enter the functions to draw. There press [F6:Draw].

Hope it helps.

### How to draw f(x,y) =x^2+y^2-2x

Hello,
Press [MENU]. Highlight the [GRAPH] icon and press [EXE]. Press [F3:Type] then [F2: r=]. Enter you expression as 1+ cos(theta). If there are any functions Y=, delete them by highlighting each one and pressing [F2:Del][F1:Yes].
Press [F6:Draw]Your cardioid is drawn on the screen. This type of graph r=f(theta) is a polar graph.
Hope it helps.
