The graph of f(x) = x² is transformed to create the graph of h(x) = -1/5(x - 1) + 7. Which description best describes the transformation?

• The graph of f is vertically compressed by a factor of 5, horizontally translated 1 unit right, vertically translated 7 units up, and reflected over the x-axis to create h.

• The graph of f is vertically stretched by a factor of 5, horizontally translated 1 unit right, vertically translated 7 units down, and reflected over the x-axis to create h.

• The graph of f is vertically compressed by a factor of 5, horizontally translated 1 unit left, vertically translated 7 units up, and reflected over the x-axis to create h.

• The graph of f is vertically stretched by a factor of 5, horizontally translated 1 unit right, vertically translated 7 units up, and reflected over the y-axis to create h.
