x values -44 through 44 produce integral values of the exponent and thus of y. This accounts for 89 points.
x=2020 makes the base 1. Even to a fractional power, it results in 1.
Zero would not work with a negative power so x=2019 is bad.
x=2018 makes the base -1 and the power odd though negative, so y is -1
These latter values bring the total to 91.
