Eddie Murphy shrugs in Detroit

Storyboard Text

  • Oh wow, it's Eddie Murphy! Hey, do you wanna help me with finding the domain for this function?
  • Sure, what is it?
  • Somewhere in Detroit...
  • y=√63-9x
  • I'm not sure, homie :/
  • ...but, I know a guy who could help us!
  • Oh that one's easy!
  • Hey man, thanks for coming, so the function is y=√63-9x
  • So you make 63-9x less than or equal to 0 (63-9x≥0)
  • Then you subtract 63 from both sides, which would make it -9x≥-63
  • After that, you divide -9x≥-63 by -9x and get x≤7
  • Wow!
  • So the domain of the function would be (-∞,7]
  • He's a genius, thank you so much!
  • Dinner on me!
  • The End
