reflect a circle about a line L through its center, then rotate it through 40◦ counterclockwise, and then reflect it once more a
bout the same line L
1 answer:
Answer:
The answer is provided in the attachments as Picture.
Step-by-step explanation:
We take a circle with a line L passing through its center and mark a point P initially on the circle.
No, we perform all the mentioned operations on the circle and note the change through the change in position of P.
The whole procedure is attached as the PNG in the answer.

The <em>correct answers</em> are:
C) No: we would need to know if the vertex is a minimum or a maximum; and
C)( 0.25, 5.875).
Explanation:
The domain of any quadratic function is all real numbers.
The range, however, would depend on whether the quadratic was open upward or downward. If the vertex is a maximum, then the quadratic opens down and the range is all values of y less than or equal to the y-coordinate of the vertex.
If the vertex is a minimum, then the quadratic opens up and the range is all values of y greater than or equal to the y-coordinate of the vertex.
There is no way to identify from the coordinates of the vertex whether it is a maximum or a minimum, so we cannot tell what the range is.
The graph of the quadratic function is shown in the attachment. Tracing it, the vertex is at approximately (0.25, 0.5875).
