- 1. The __________ of a parabola is the chord through the parabola’s focus and is perpendicular to the axis. Its length is often denoted by |4p|. (hint: 2 words)
- 3. The segment between the vertices of an ellipse is called the ________ axis. It has a length of 2a.
- 6. This is the type of conic defined as a set of points in a plane equidistant from a fixed point and a fixed line.
- 9. A relation between two sets for which each element from the first set is associated with exactly one element value of the second set.
- 12. A ______ is the graph of a degenerate case of a circle with radius = 0.
- 14. It is a type of function whose graph is a straight line. The function type is represented by the form f(x) = mx + b.
- 15. It is a type of function whose value is a constant raised to the independent variable (x) exponent. This function type is in the form f(x) = a · bX.
- 17. The line through the focus and the vertex of a parabola is called the ____. It is a line of symmetry that is perpendicular to the directrix of the parabola.
- 18. The surname of the skilled teacher handling all Grade 11 Mathematics classes.
- 19. This is the type of conic defined as a set of all points that are at a fixed distance (known as radius) from a fixed point.
- 21. ________ - defined functions are functions represented by a combination of equations, each corresponding to different parts of the domain.
- 22. The ______ axis of a hyperbola is the segment between the vertices that passes through the two foci.
- 25. The ______ of an ellipse is the ratio of the undirected distance between the foci to the undirected distance between the vertices. This indicates how much a conic section varies from being circular and is often denoted by ‘e’.
- 26. The __________ of a function is the set of all possible values of the independent variable, x, that will output real y-values or dependent variables.

- 2. Two intersecting lines that the branches of a hyperbola approaches but never touches are called ________.
- 4. The segment between the co-vertices of an ellipse is called the ________ axis. It has a length of 2b.
- 5. It is a type of function whose graph is a parabola. The function type is represented by the form f(x) = ax2 + bx + c.
- 6. The first name of the owner of this output, and she is often the attendance-checker of Mathematics L1-B synchronous classes.
- 7. The __________ of a parabola indicates the direction in which the parabola opens; it mainly includes up, down, left, or right.
- 8. A ________ function is a type of function whose output value is the same for every input value.
- 10. The __________ of a function is the set of all possible output values of the function (dependent variable).
- 11. This is the type of conic defined as a set of points on a plane whose sum of distances from two fixed points (foci) is a constant.
- 13. A ________ function is created by composing one function within another function.
- 16. As a plane intersects the surface of a cone, the obtained cross-sections or curves are called __________.
- 20. The distance from a point on the parabola to this FIXED LINE equates the distance from the same point on the parabola to a fixed point (focus). The fixed line is called ______.
- 23. This is the type of conic defined as the set of all points in a plane the difference of whose distance from two fixed points (foci) is constant.
- 24. The equation of a circle in the format (x - h) 2 + (y - k) 2 = r 2 is called the center - ______ form.
