Question

How do u write a function for the reflection across the y axis

Answer 1

Answer:

Make the transformation:

$g (x) = f (-x)$

Step-by-step explanation:

If you have a function f(x) and you want to reflect the function f (x) on the y-axis then you must do the following transformation:

$g (x) = f (-x)$

Where g(x) is the transformed function

Then the function g(x) will be equal to the function f(x) reflected on the y axis
