Answer:
Step-by-step explanation:
Given a function:
To find:
Function whose graph is a reflection in the y -axis for the given function = ?
Solution:
First of all, let us learn about the reflection of a point () in y axis.
For example, let us consider a point (3, 2) on the coordinate axis.
The reflection of this point in y axis will be (-3, 2)
OR
In other words, <em>To find the image of a point in y axis</em>:
the x coordinate is made of negative sign and y coordinate remains the same.
A line is nothing but a number of points joined together.
So, if we want to find reflection of a line or linear function in y axis, we just make the sign of x as negative.
Given that
We can write it as:
To find its reflection:
Please refer to the attached graphs of and
.
So, the answer is:
