How do you find the domain and range for equations like: Y=X^1/7 and Y=5√(X-4) +2 I have no idea where to start

Think, where would this be undefined...

Never? All Real Numbers?

Oh for the domain, okay! How would you find range algebraically?
Rizags
  • Rizags
for the first one, intuitively, one can see it is also all reals
Jellybot23
  • Jellybot23
Okay, yo just got that from the graph? How about the second?
Rizags
  • Rizags
yes. for the second, the "x-4" under the radical must always be greater than or equal to 0
Jellybot23
  • Jellybot23
So the range would be {X: X>4} (greater than or equal to, I didn't know how to make that sign haha)
Rizags
  • Rizags
yep. and for range plug in x=4 for minimum
Jellybot23
  • Jellybot23
Awesome thank you! So the range for any of those problems like the second one would be found by taking what's under the radical knowing it cannot be great than or equal to zero?
Rizags
  • Rizags
only if the radical has an even index.
Rizags
  • Rizags
medal plz
Jellybot23
  • Jellybot23
What do you mean by even index (sorry)
Rizags
  • Rizags
no problem.\[\sqrt[2]{x}\] ^ Has an even index\[\sqrt[3]{x}\]^has an odd index. Odd indices can accept an real number, even ones accept all reals greater than or equal to 0

Okay! I see! Thank you :)
