Find the equation of each of the following parabolas. (1 whole)
1. Vertex (5, -2); focus (4, -2)
-
3
2. Vertex (3, 1); focus (1,1)
3. Vertex at (-3, 1) and passes through point (5, 5) with the axis
parallel to the x-axis.
4. Vertex at (3, -2) passes through point (7, -6) with the axis parallel
to the y-axis.
5. A car headlight mirror has a parabolic cross section with the bulb
located at the focus of the parabola. If the bulb is directly 2 cm
above the vertex, how wide is the mirror if it is 8 cm deep?
