The graphs of two sine functions are shown below. The function whose graph is B was obtained from the function whose graph is A by one of the following changes. That change was the addition of a negative constant a change in amplitude a phase shift a period change

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

no i do not : ( what is it?

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
