What does a vertical compression by a factor of 1/2 do to a function?

• It reduces the height of the graph by half, making it flatter.

• It doubles the height of the graph, making it steeper.

• It shifts the graph to the left by half its width.

• Vertical Stretch by a factor of 2.

• Vertical Compression by a factor of 2.

• Horizontal Stretch by a factor of 2.

• Reflection over the x-axis.

What is the effect of a reflection across the x-axis on a function?

• It flips the graph of the function over the x-axis.

• It shifts the graph of the function to the right.

• It stretches the graph of the function vertically.

• It rotates the graph of the function 180 degrees.

How does the transformation f(x) = -f(x) affect the graph?

• It reflects the graph across the x-axis.

• It shifts the graph to the right.

• It stretches the graph vertically.

• It reflects the graph across the y-axis.

What is the effect of subtracting a constant from the input, such as f(x - c)?

• It translates the graph horizontally to the right by c units.

• It translates the graph vertically upwards by c units.

• It reflects the graph across the x-axis.
