Unit 7 Lesson 12 Practice Assignment

What happens to the parabola when you multiply its equation by a number bigger than 1?

• Graph moves UP
• Graph gets WIDER
• Graph moves DOWN
• Graph gets NARROWER

When you add a number to y=x²  what happens to the graph?

• Graph moves UP
• Graph moves to the RIGHT
• Graph moves DOWN
• Graph moves to the LEFT

When you subtract a number from y=x²  what happens to the graph?

• Graph moves UP
• Graph moves to the RIGHT
• Graph moves DOWN
• Graph moves to the LEFT

What is the turning point of this graph?

• x=2
• y=-3
• (2, 1)
• y=1

In vertex form, what effect does the k have on the graph?

• Translates vertically
• Translates horizontally
• Dilates (stretches)

• More Narrow (stretches)

• More Wide (compresses)

Describe the transformation of the graph  y = (x)³  + 6

• Right 6
• Left 6
• Up 6
• Down 6

Find the equation of the parabola that has moved...

3 units up

• Down 4

• Left 4

• Up 4

• Right 4

When you subtract a constant from y=x²  what happens to the graph? Eg  y = x² - 2

• Graph moves UP
• Graph moves to the RIGHT
• Graph moves DOWN
• Graph moves to the LEFT
