Shifts and Properties of Parabolas

The video tutorial demonstrates how to adjust the leading coefficient and vertex coordinates to align a blue parabola with an orange one. It covers shifting parabolas by modifying the y-value and explains how subtracting or adding values affects the parabola's position. The tutorial also shows how to align vertices and adjust the scaling factor to match the growth rate of the parabolas. By experimenting with these adjustments, viewers can learn how to manipulate parabolas effectively.

What is the primary goal when adjusting the leading coefficient and vertex coordinates of a parabola?

• To make the parabola wider

• To match the parabola with another parabola

• To change the color of the parabola

• To make the parabola a straight line

How does subtracting a value from y affect the position of a parabola?

• It shifts the parabola to the right

• It shifts the parabola down

• It shifts the parabola to the left

• It shifts the parabola up

What happens to a parabola when you add a value to y?

• It shifts right

• It shifts left

• It shifts down

• It shifts up

When you subtract a value from the x-coordinate, in which direction does the parabola shift?

• To the left

• Downwards

• To the right

• Upwards

Adding a value to the x-coordinate of a parabola results in which shift?

• Left

• Up

• Right

• Down

What is the vertex of the parabola in the example given?

• x=-4, y=-3

• x=-3, y=-4

• x=0, y=0

• x=4, y=3

Why do the parabolas still not match after aligning the vertices?

• The color is different

• The vertex is not aligned

• The parabolas are not parabolas

• The scaling factor is incorrect

What happens when the scaling factor is set to zero?

• The parabola becomes a flat line

• The parabola shifts downwards

• The parabola disappears

• The parabola shifts upwards

If the scaling factor is increased to three, what is the effect on the parabola?

• It shifts to the left

• It grows too fast

• It becomes a flat line

• It grows too slow

What is the correct scaling factor to match the growth rate of the parabolas?

• 3

• 1

• 2

• 0
