Slide 1  How to Graph a Parabola in Vertex form with the calculator.
 By: Zykiah Kursh

Slide 2  Example of a problem in Vertex form
 Y=a(xh)2+k

Slide 3  Step one
 The first step is to write down your equation.
 Y= 3 (x+1)

Slide 4  Step 2
 Next, Make a X & Y chart.
 X
 Y

Slide 5  Step 3
 If the number in parenthesis is a negative or positive, you do the opposite of that number and put that opposite number on the x side of the table. (For example)
 Y= 3 (x+1)
 1
 x
 y
 1

Slide 6  Step 4
 After that you can put any numbers you would like in the x and y chart but it can’t be too big of a number.
 X
 Y
 0
 1
 2

Slide 7  Step 5
 Then, you replace “x” with those numbers (one at a time) in the calculator.
 Like the example to the right

Slide 8  Step 6
 After that you will have all the outcomes (Y) listed
 Problem
 Y= 3 (x+1)
 X
 Y
 0

Slide 9  Step 7
 FINALLY! Those are your points for your graph, now you graph them!
 Problem Y= 3 (x+1)

Slide 10
 ….AND THAT’S HOW YOU MAKE A PARABOLA IN VERTEX FORM!
