Quadratic Transformations Day 2 Quick Check

What happens to the graph when the value of "a" is bigger than 1?

• The graph stretches which means it gets skinnier.

• The graph stretches which means it gets fatter.

• The graph compresses which means it gets skinnier.

• The graph compresses which means it gets fatter.

What happens to the graph when the value of "a" is between 0 and 1.

• The graph stretches which means it gets skinnier.

• The graph stretches which means it gets fatter.

• The graph compresses which means it gets skinnier.

• The graph compresses which means it gets fatter.

What happens to the graph when "a" is negative?

• The graph reflects "flips" over the x-axis.

• The graph reflects "flips" over the y-axis.

• The graph reflects "flips" over the axis of symmetry.

• The negative "a" does not change the graph.

• Vertical stretch of 11, making the graph skinnier.

• Vertical compression of 11, making the graph fatter.

• Vertical reflection of 11, flipping the graph over the x-axis.

• Vertical reflection of 11, flipping the graph over the y-axis.
