Step-by-step explanation:
For this case we must determine the inverse of the following function:
Step 1:
We would write
or
Step 2:
We clear x:
Step 3:
"x" and "y" are exchanged:
The inverse is:
Answer:
Both are correct.
Step-by-step explanation:
In the point (4,-2) and (4,-7), the x-coordinates are same. So, the distance between these points is the absolute difference between the y-coordinates of these points.
So, Laura is correct.
In the point (2,3) and (-9,3), the y-coordinates are same. So, the distance between these points is the absolute difference between the x-coordinates of these points.
So, Ryan is correct.
Hence, both are correct.
