teh discriminate doesnt define a domain tho
amistre64
  • amistre64
discriminate tells you if it hits the x axis; but domain tells you what you can use to find y
amistre64
  • amistre64
a graph that floats above the x axis still has a domain of all valid x's; otherwise you simply couldnt have the graph

amistre64

The domain of your function tells you all the valid inputs that make it work right. Those values for this function have no restrictions so any number will work
