What is the domain and range of #y = 3x+6#?

1 Answer

#"dom: " x in RR#
#"ran: " y in RR#

Explanation:

  • The domain is defined as the set of all the possible x-values that can be input into the function.
  • The range is defined as the set of all the possible y-values that can be input into the function.

Linear functions generally have a domain and range of #RR# (all real values). Unless there is a restriction of the domain of the linear function, the domain and range of #y# will be #RR#.
