Answer:
Option 3
Explanation:
Option 3 is not a function as there is no regular pattern like the other functions. In mathematics, instructions in a function are constant and cannot be changed meaning that there will always be some kind of pattern with each produced value.
Let's see an example:
For each value of x, each outcome will have gone through the same process. The first 5 values of this function will be 3, 5, 7, 9, 11.
The pattern here is that every outcome is an odd number.
Returning to the question, each option (excluding option 3) has a pattern.
Option 1: Y is always 1 and X is increasing by 1 each time, starting from 0.
Option 2: X is always 0 and Y is increasing by 1 each time, starting from 0.
Option 4: X and Y are increasing by a factor of 2 each time, starting from 0.
But, there is no pattern with option 3.
I hope this helps.
