Questions and Answers

What are the zeros of the function?

The x-intercepts of the graph of a function.

What does the zero-product property state?

  • If $ab=1$, then neither $a$ nor $b$ can equal zero (correct)
  • If $a+b=0$, then $a=-b$
  • If $ab=0$, then $a=0$ or $b=0$ (correct)
  • If $a*b=1$, then $a=1/b$
