Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y). If a point B(x, y) is reflected over the y axis, the new point is at A'(-x, y).
Triangle A has vertex at (-4, -2), (-4, -5) and (-2, -5). If triangle A is reflected in the x axis to give triangle B, the vertex of triangle B is (-4, 2), (-4, 5) and (-2, 5).
If triangle B is reflected in the y axis to give triangle C, the vertex of triangle C is at (4, 2), (4, 5) and (2, 5). Hence the transformation is:
(x, y) ⇒ (-x, -y)
Assessing the regression model on data other than the sample data that was used to generate the model is known as cross-validation
<h3>How to complete the blank?</h3>
From the question, we have the following highlights:
- Sample data, not used
- The model is a regression model
When the sample data is not used in a regression model, then the term is known as cross-validation.
Hence, the term that completes blank is cross-validation
