Which graph shows this set of transformations applied to the parent cosine function?
l A reflection across the x-axis
l A shift of 2 units up
l A vertical compression by a factor of 0.5
On a coordinate plane, a cosine curve has a maximum value of 2.5 and a minimum value of 1.5. It crosses the y-axis at (0, 2.5) at its maximum point.
