Answer:
<h3>Right π over 2 Up 2.</h3>
Step-by-step explanation:
We are given a trigonometric function f(x) = −3 cos(2x − π) + 2.
We need to explain the transformations in the given function being applied.
We can see that 2 is being added to −3 cos(2x − π) in th given function.
<em>According to rules of transformations, y=f(x)+D, shifts D units up if D is a positive number.</em>
Therefore, for adding 2 in −3 cos(2x − π), it would shift 2 units up.
Let us see other transformation being applied there.
We can see that π is being subtracted in parenthesis from 2x.
<em>According to rules of transformations, y=f(x-C), shifts C units right if C is a positive value.</em>
Therefore, on subtracting π from 2x in −3 cos(2x) inside parenthesis, the function shifts π units right.
Therefore, correct option for transformations would be :
<h3>Right π over 2 Up 2.</h3>
