Across
  1. 3. of the point, the x and the y coordinate.
  2. 5. a decimal number that contains a finite number of digits after the decimal point
  3. 7. notation, asymptotic notations that specify upper-bounds for functions and running times of algorithms.
  4. 8. plane a graph with two axes
  5. 9. the point where the axes of the system intersect.
  6. 10. intervals An interval is unbounded if both endpoints are not real numbers.
Down
  1. 1. numbers all the real numbers which are not rational numbers and cannot be expressed as the ratio of two integers.
  2. 2. notation, However, the difference is that Big-O may be asymptotically tight while little-o makes sure that the upper bound isn't asymptotically tight.
  3. 4. line the line whose points are the real numbers.
  4. 6. inverse a number that when added to a given number gives zero and known as the opposite number.
