Question

Which equation represents the graph of y= cosx reflected across the x-axis then shifted vertically down by 2 units?

Note: Attachment below are the answer choices

Answer 1

y = -cos(x) -2

Explanation:

Multiplying the function value by -1 reflects it across the x-axis. Adding -2 to the function value shifts it down by two units.

reflected: y = -cos(x)

then shifted: y = -cos(x) -2
