Which of the following is the equation of a parabola whose vertex is at (5, 4)?

  1. Option A
  2. Option B
  3. Option C
  4. Option D
  5. Option E

Answer(s): A

Explanation:

The equation of a parabola with its turning point five units to the right of the y-axis is written as y = (x -5)2. The equation of a parabola with its turning point four units below the x-axis is written as y = x2- 4.
Therefore, the equation of a parabola with its vertex at(5, 4) is y= (x - 5)2 4.



If

  1. 6.
  2. 4.
  3. 0.
  4. 24.
  5. 28.

Answer(s): D

Explanation:

Ifb3- 64, then, taking the cube root of both sides, b = -4. Substitute-4for b in the second equation:



Eggs Found in a Hunt Over Time

The scatter plot above shows how many eggs were found in a hunt over time. Which of the labeled points represents a number of eggs found that is greater than the number of minutes that has elapsed?

  1. A
  2. B
  3. C
  4. D
  5. E

Answer(s): E

Explanation:

The point that represents a number of eggs found that is greater than the number of minutes that has elapsed is the point that has a y value that is greater than its x value. Only point E lies farther from the horizontal axis than it lies from the vertical axis. At point E, more eggs have been found than the number of minutes that has elapsed.



The point (6, 3) could be the midpoint of which of the following lines?

  1. a line with endpoints at (0, 1) and (12, 2)
  2. a line with endpoints at (2, 3) and (6, 1)
  3. a line with endpoints at (6, 0) and (6, 6)
  4. a line with endpoints at (6, 3) and (6, 3)
  5. a line with endpoints at (3, 3) and (12, 6)

Answer(s): C

Explanation:

The midpoint of a line is equal to the average of the x-coordinates and the average of the y-coordinates of the endpoints of the line. The midpoint of the line with endpoints at and(6, -6)is
