Answer:
Step-by-step explanation:
Given : y = cos x
To Find : Which equation represents the graph of y = cos x flipped across the x-axis then shifted vertically up by 2 units?
Solution :
y = cos x
Since we are given that the graph of y = cos x flipped across the x axis
So it will be lying in negative x axis
So, equation becomes y= - cos x
Now shift the obtain graph vertically up by 2 units
When the graph ships vertically up by some units so f(x) becomes f(x)+b
Where b is the units by which the graph shifts
Since the obtained graph is f(x) = y = -cos x
So after the vertically upward shift by 2 units :
y = -cos x+2
Thus Option A is correct .
