1. 1-A)The graph of the function y =2x is shown below.
If the line is translated 3 units up, which equation will best describe the new line?
A y =2x + 3
B y =2(x + 3)
E y =2x -3
WE ARE GOING TO USE A TI-82 CALCULATOR TO ANSWER THIS QUESTION.

2.  SYMBOL. NOW, LET US GO BACK TO THE PROBLEM 1)PRESS Y= . THEN,
HOW TO DO IT WITH A CALCULATOR(TI-82):
1)PRESS Y= . THEN,
ENTER EACH EQUATION.
MAKE SURE YOU PUT FRACTIONS IN ( ) USING
 SYMBOL.
2)PRESS GRAPH.
NOW, LET
US GO BACK
TO THE PROBLEM
3)COMPARE THE GRAPH WITH THE ONE GIVEN IN THE PROBLEM.
CALCULATOR: HOW TO GRAPH A GIVEN EQUATION

3. THIS ONE LOOKS LIKE 3 UNITS UP!
1-A)The graph of the function y =2x is shown below.
If the line is translated 3 units up, which equation will best describe the new line?
A y =2x + 3
B y =2(x + 3)
DIFFERENT SHAPE!
DIFFERENT SHAPE!
E y =2x -3 C D A B E
DOWN NOT UP!
THIS ONE LOOKS LIKE 3 UNITS UP!
TOO MANY UNITS UP!

4. f( x) =3x -1 1-B)What is the range of the function
when the domain is {-3, -2, -1} ?
A {-9, -6, -3}
B {-10, -7, -3}
C {-10, -7, -4}
D {8, 5, 2}
E {-1, 0, 1}
WE ARE GOING TO USE A TI-82 CALCULATOR TO ANSWER THIS QUESTION.

5. Y1 TAKES THE PLACE OF f( x)
HOW TO DO IT WITH A CALCULATOR(TI-82):
1)PRESS Y=, ENTER THE RIGHT SIDE OF
f( x) =3x -1 IN Y1 .
Y1 TAKES THE PLACE OF f( x)
3)ARROW DOWN AND
RIGHT TO Ask FOR
Indpnt: AND PRESS ENTER.
2)PRESS 2ND , THEN WINDOW.
4)PRESS 2ND , THEN GRAPH.
LET US LOOK
AT THE PROBLEM
AGAIN.
5)ENTER THE DOMAIN {-3, -2, -1} IN X COLUMN. THE
CALCULATOR GIVES YOU THE RANGE IN Y COLUMN.
CALCULATOR: HOW TO FIND THE RANGE

6. HERE f( x) =3x -1 1-B)What is the range of the function
when the domain is {-3, -2, -1} ?
A {-9, -6, -3}
B {-10, -7, -3}
C {-10, -7, -4}
D {8, 5, 2}
E {-1, 0, 1}
NOTE: IF THE DOMAIN INCLUDES FRACTIONS, PUT THEM IN ( )! THE NUMBERS IN THE RANGE WILL BE IN DECIMAL FORM.
YOU ENTER THE Domain
HERE
THE CALCULATOR PUTS THE Range FOR THE GIVEN DOMAIN HERE
OBJECTIVE 1

7. 1-C) Given the relation between X and Y in the table below, What is the value of Y when X= -13?65
-19 29 26
-35 X Y -1 -7 3
-19 -2 -4 5
-25
we use a TI-82 to find the value of x:
1)Press STAT, 1. Enter the X values in L1 and Y values in L2 .
2) Press 2nd STAT PLOT,1, Enter, ZOOM, 9.
It seems that we can draw a straight line through all 4 points. So, we will find a linear relation between Y and X. we do so using a TI-82 STAT feature.
3) Press STAT, right arrow, 5, Enter.
5)Press 2nd TblSet.Change Indpnt to Ask
This is the equations of the relation between X and Y
Follow step 4 to put the equation in Y1
6) Press 2nd TABLE. Enter –13 for X and notice the value of Y which is 29.
4) Press Y= , VARS, 5, right arrow twice, 7.
The correct answer is C.
