How to Reflect the Function Over the Y-axis. When we have to reflect a function over the y-axis, the points of the y coordinates will remain the same while we will change the
Since we do reflection transformation across the y-axis, we have to replace x by -x in the given function. y = √x. Step 2 : So, the formula that gives the requested transformation is. y = √-x. Step 3 : The graph y = √-x can be obtained by

Scan your problem
The first step to solving any problem is to scan it and break it down into smaller pieces.
How do you reflect over the y-axis in an equation? To flip or reflect (horizontally) about the vertical y-axis, replace y = f(x) with y = f(-x). What are the coordinates of the y-axis?

The formula for this is: {eq}(x,y) \rightarrow (-x,y) {/eq}. To reflect an equation over the y-axis, simply multiply the input variable by -1: {eq}y=f(x) \rightarrow y=f(-x) {/eq}.
