Question
Find g(x), where g(x) is the reflection across the y-axis of f(x)=x–5.g(x)=–x+5g(x)=x+5g(x)=–x–5g(x)=x–5Submit
Solution
The reflection of a function across the y-axis is found by replacing x with -x in the original function. So, if f(x) = x - 5, then the reflection of f(x) across the y-axis, g(x), is found by replacing x with -x in f(x).
So, g(x) = -x - 5.
