When we have an equation , a function , or an inequality such as f(x) , g(x) , x , y , = , < , > , ≤ , ≥

X is the input and y is the output , the ordered pair is (x,y) , is goes first.

We use it to find:

The graph for a function or relation. Write y instead of f(x), the graph of a function f is the set of all points (x, f(x)). Sometimes they use g(x) , h(x) , p(x) , they are the same thing. they all means y.

Graph Relation GR STEPS:

1- Ctrl N

2- Add Graph

3- del 6: Relation

4- replace f(x) by y and type the equation or the inequality the way it is.

 

Example 1: 

Graph the following equation f(x)=3x+4 ?

Solution 1:

 

 

 

Example 2: 

Graph the following inequality 3y + x < – 4 ?

Solution 2:

Practice :

GR-1 Graph order pairs on the Coordinate plane (x,y) and find Quadrant I,II,III,IV.

GR-2 Graph Linear , Quadratic and Exponential equations and functions.  

GR-3 Graph inequalities and a system of linear equations and inequalities.   

GR-4 Graph Quadratic and linear equations and find if the line is a factor.

GR-5 Graph Linear Equations , compare the lines graphed ( steeper – less steep – parallel – shifted up – shifted down )

GR-6 Graph Quadratic Equations , compare the parabolas graphed ( narrower , wider , up , down , right , left )

When we have an equation , a function , or an inequality such as f(x) , g(x) , x , y , = , < , > , ≤ , ≥

We Graph it and Then we Trace the graph. Menu 5 1 

 

We use it to find:

1- y-intercept

2- The point (x,y) , if you are given x you can find y and vice-versa.

3- Solve Linear Equations.

Graph Relation Trace GRT STEPS: y-int and point (x,y)

1- Ctrl – N ( If it asks to if you want to save click No )

2- Add Graph , Enter

3- del 6: Relation ( Remember f(x)=y )

4- Write down the relation the way it is. Enter

5- Menu 5 ( Trace ) 1 ( Trace Graph ) 

6- Enter → This always take you to y-intercept (0,y-int)

7- Press Esc ( Top left button in the calculator )

8- Hover with mouse and move the y-intercept point to an empty space in the screen. and you will get the point (x,y).

9- Double click where you want to change the x or the y as asked in the question.

 

Example 1: 

for the Graph of the linear equation 2x-6y=3 , What is the value of y when x=-3 ?

Solution 1:

Example 2: 

Evaluate f(4) for the function f(x)=½x-6 ?

Solution 2:

Graph Relation Trace GRT STEPS: Solving Linear Equations

1- Ctrl – N ( If it asks to if you want to save click No )

2- Add Graph:2. Enter

3- del 6: Relation ( Remember f(x)=y )

4- Write down the equation ( make sure to switch the letter used in the equation to x ) . Enter

5- Menu 5 ( Trace ) 1 ( Trace Graph ) Enter

 

Example 3: 

What is the solution to the equation 8x-3(2x-4)=3(x-6) ?

Solution 3:

 

 

Practice :

GRT-1 Graph the function and find y-intercept and find point (x,y)

When we have an equation , a function , or an inequality such as f(x) , g(x) , x , y , = , < , > , ≤ , ≥

We Graph it and Then we Trace the graph. Menu 6

 

We use it to find:

1- Slope or the rate of change (rate).

2- Zero or the x-intercept ( root or solution ).

3- Vertex, Maximum or Minimum for Quadratic functions Graphs.

4- Intersection (x,y) between 2 lines

Graph Relation Analyze GRA STEPS

1- Ctrl – N ( If it asks to if you want to save click No )

2- Add Graph:2. Enter

3- del 6: Relation ( Remember f(x)=y )

4- Write down the relation the way it is. Enter

5- To find the Slope , press Menu 6 ( Analyze ) 5 ( dy/dx ) , click on the line and get your answer.

6- To find the Zero, press Menu 6 ( Analyze ) 1 (zero) , a vertical dotted line appears , Enter before the x-intercept  and move to after x-intercept and press enter. you would see the word zero in yellow.

Note: sometimes you might need to zoom out the graph ( Menu 4 4 ). if needed!

Example 1: 

What is the Slope of the line with the equation y+4=4x ?

Solution 1:

 

Example 2: 

What is the zero of the line with the equation y+4=4x ?

Solution 2:

Example 3: 

What is the intersection of the system of the linear equations 3x+y=-1 and x+2y=-7 ?

Solution 3:
