Question

Which table does not show y as a function of x

Answer 1

It is Table H because if you have an x value that equals two different y values then it is not a function.

Hope this helps.

Answer 2

Table H

for y to be a function of x, every x input value has to map to one and only 1 output y value

at table H, x = -0.2 maps to both 5.8 and 8.1 (both ends of the table)

so table H is not y as a funtion of x
