How to determine the image of the transformation
From the question, we have the following parameters that can be used in our computation:
A(1, 1), B(1, 3) C(3, 1)
First, we graph the triangle ABC
This is the given figure 1 in the question
Next, we dilate the coordinates by 2
This means that we multiply the coordinates by 2
So, we have
A'(2, 2), B'(2, 6) and C'(6, 2)
Lastly, we reflect across the y-axis
This means that we negate the x-coordinates
So, we have
A''(-2, 2), B''(-2, 6) and C''(-6, 2)
