Answer:

See below

Explanation:

I don't know why there are double braces in the expression, because they are not necessary.

#y = 2/5x - 4/5#

This is just a linear function, so its domain and range are all of #RR#

Domain#-> {x in RR}#

Range#-> { y in RR}#

All continuous linear functions have domain and range #RR# unless the gradient is #0# or undefined .i.e. perpendicular to the #x# axis.
