When we reflect a point P(x,y) over the x-axis, its coordinates are transformed as:
![P(x,y)\rightarrow P^(\prime)(x,-y)](https://img.qammunity.org/2023/formulas/mathematics/college/2f116h16c6evkr2fn1rzil2aj31v00vywe.png)
Thus, the x-coordinate remains the same, while the y-coordinate is the opposite of the original one.
In this problem, we need to determine the coordinates of point E after it is reflected over the x -axis.
Since the coordinates of E are (1,4), after the reflection they are transformed as:
![E(1,4)\rightarrow E^(\prime)(1,-4)](https://img.qammunity.org/2023/formulas/mathematics/college/v0llo15heuxl1z7mmq5ffrsd7lausx7iwt.png)
Therefore, after that reflection, we obtain the point:
![E^(\prime)(1,-4)](https://img.qammunity.org/2023/formulas/mathematics/college/738eusrtrt2uy167gydxie5nx8zfsemmna.png)
