quadrant
The four parts of a grid divided by the axes. Each of these quadrants have a number designation:
  • First quadrant - contains all the points with positive x and positive y coordinates.
  • Second quadrant - contains all the points with negative x and positive y coordinates.
  • Third quadrant - contains all the points with negative x and negative y coordinates.
  • Fourth quadrant - contains all the points with positive x and negative y coordinates.
quadratic function
A function of the form f(x) = ax2 + bx + c where a is not equal to zero (in which case the function turns into a linear function).
quadrilateral
A polygon that has four sides.
quotient
When performing division, the number of times one value can be multiplied to reach the other value represents the quotient. For example, when dividing 7 by 3, 3 can be multiplied twice, making 6, and the remainder is 1, so the quotient is 2.
