Expert Solution
Step 1

Given:

The input is 8 and the output is 26.

From the given equations, it can be stated that:

x is taking the input.

And, y gives the output.

Total 5 equations are given.

Checking the rule for each by putting the given input value in x.

1)-

y=4x-2

replacing x by 8, we have:

y=48-2y=32-2y=30

The output is 30.

Therefore, this is not the rule.
