Question

U6 Review HW: Practice with Parabolas

1. What are the coordinates of the vertex?
2. What are the coordinates of the focus?
3. What is the equation of the directrix?
a. y = 0
b. y = 1
c. y = 2
d. y = 4
4. Write the equation of the parabola.
2
5. Is the point (2, 4) the same distance from (0, 4) and the line y = 2? Explain why or
why not.
6. Is the point (4, 6) on the parabola? Explain why or why not.
X

Answer 1

the vertex is the highest or lowest point on theparabola. (0,3)

The focus is (0,4)

The directrix is the fixed line. Equation y=2

by definition, all points on the parabola are equidistant from a fixed point (focus) and fixed line (directrix)
