Question

The function table below is intended to represent the relationship y = 5x-1. However, one of the entries for y does not correctly fit the relationship with x.

Answer 1

We have the following info:

x y

1 4

2 8

3 14

4 19

The relationship is:

y= 5x-1

If we look for the second row we have this:

y= 5*2 -1 = 10 -1= 9

Then we can conclude that the incorrect value is:

x=2
