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

  y = -cos(x) -2

Step-by-step 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

nope
