Graph the image of the figure after a dilation with a scale factor of 2 centered at (−2,−2). Use the Polygon tool to graph the q
uadrilateral by connecting all its vertices.

Answer:
see below
Step-by-step explanation:
Every vertex moves twice as far from the center of dilation as it is in the pre-image.
Perhaps the easiest image point to find is the one at lower left. In the pre-image it is 2 units left of the center of dilation, so the image point will be 2×2 = 4 units left of the center of dilation. It will be located at (-6, -2).
Other points on the image can be found either by reference to the center of dilation, or by reference to known image points. For example, the next point clockwise is 1 left and 4 up in the pre-image, so will be 2 left and 8 up from (-6, -2) in the image. That is, the pre-image point (-5, 2) becomes image point (-8, 6). You will note that (-5, 2) is 3 left and 4 up from the center of dilation, and that (-8, 6) is 6 left and 8 up from the center of dilation (twice as far away).

Answer:
A.
Step-by-step explanation:
A rational-polynomic function is a function of the form:
(1)
There are three important remarks on this kind of function:
1) when function passes through the x-axis.
2) If , then the function
has a vertical asymptote.
3) The horizontal asymptote is a linear function of the form .
In accordance with the graph, the function has two vertical asymptotes at and
, numerator becomes zero for
and horizontal asymptote is
as grade of numerator is less than grade of denominator.
Hence, we conclude that rational function is <em>. </em>(Correct answer: A)
