OA. The graph of g is the graph of fhorizontally stretched by a scale
factor of 3 and reflected over the x-axis.
OB. The graph of g is the graph of fhorizontally stretched by a scale
factor of 3 and reflected over the y-axis.
C. The graph of g is the graph of fvertically stretched by a scale
factor of 3 and reflected over the x-axis.
D. The graph of g is the graph of fvertically stretched by a scale
factor of 3 and reflected over the y-axis.
