Sagot :

Answer:

A.

Step-by-step explanation:

We must find the function to see if it's Sine or cosine function.

1.Here when the graph is I'm the third quadrant, the function seems to be a reflection of the graph in 4th quadrant, odd functions are reflected about orgin. and Sine is a odd function so that eliminates C and D.

2. The midline is -2 because the y intercept is -2 so the answer is A.
