Question

question 6 of 10
the ____ is the extreme point on half of a hyperbola.
a. focus
b. vertex
c. directrix

Explanation:

A hyperbola has two branches (halves). The vertex is the extreme point on each half of the hyperbola. A focus is a fixed point related to the hyperbola's definition (the set of points where the absolute value of the difference of distances from two foci is constant). A directrix is a line used in the conic - section definition of a hyperbola (but not the extreme point on the half - hyperbola).

Answer:

B. vertex
