Question

Which equation represents the graph of y = sin x flipped across the y-axis then shifted vertically up by 2 units
A. y = sin(x - 2)
B. y = -sin x - 2
C. y = sin x - 2
D. y = sin(-x) + 2

Answer 1

\[f(x) \rightarrow -f(x)\]Flips over y-axis

\[f(x)\rightarrow f(x) + n\]Shifts up n units

Answer 2

Also, \[-\sin(x) = \sin(-x)\]

Answer 3

Then it could be B or D

Answer 4
