Math Problem Statement
Solution
The question asks for the equation of the reflection of the function , where , over the line .
Step-by-Step Solution:
-
Find the reflection formula: To reflect a function across the line , we use the formula: where is the value of the line over which we are reflecting, and in this case, .
-
Apply the reflection: The function is reflected across , so:
-
Simplify the expression: Subtract from 6: To simplify further, we can rewrite this expression as: Simplify the numerator: So:
Thus, the equation of the reflected function is:
