Find the image of the point `(1,3,4)` in the plane `2x-y+z+3=0.`

Explanation

To find the image of the point \( (1, 3, 4) \) in the plane given by the equation \( 2x - y + z + 3 = 0 \), we can follow these steps:

### Step 1: Identify the coefficients of the plane equation
The plane equation can be rewritten in the form \( ax + by + cz + d = 0 \):
- Here, \( a = 2 \), \( b = -1 \), \( c = 1 \), and \( d = 3 \).

### Step 2: Write down the coordinates of the point
The coordinates of the point are:
