Question

The graph f(x) = x^2 was transformed to create the graph g(x) = - 1/5x^2.

Which statement describes this transformation?

A. A reflection over the x-axis and a horizontal compression.
B. A reflection over the y-axis and a vertical compression.
C. A reflection over the y-axis and a horizontal compression.
D. A reflection over the x-axis and a vertical compression

Answer 1

The negative sign reflects the graph over the x axis and the 1/5 in front of the x widens the line causing a vertical compression.

Answer: D. A reflection over the x-axis and a vertical compression
