Question

Which equation represents the graph of y=cos x flipped across the x- axis then shifted vertically up by 2 units

y = -cos x + 2

y = -cos x - 2

y = cos(x - 2)

y = cos(-x) + 2

Answer 1

flipping across the x-axis ---> multiply the entire function by -1
shift vertically up 2 units --> add 2 to the entire function
