Hello,
I believe the function shown in the table is B. Neither Linear no Exponentional
The function table certainly isn't linear because the rate of change for y with respect to x doesn't remain constant for a linear function.
The function table also isn't exponentional because the ratios of the y-values (outputs) aren't constant. (128/72=1.7...8,72/32=2.25,32/8=4...)
