Answer:
Reflection over the Y axis-
Step-by-step explanation:
The vertex is the minimum or the maximum point of the parabola.
<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

The standard form of a parabola is

The x coordinate of the parabola is calculated using:

The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:

At the end of the calculation,
x and f(x) represent the horizontal and the vertical coordinates of the vertex.
Take for instance:

The x-coordinate of the vertex is:




The y-coordinate is:



So, the vertex of
is (-1,11)

He needs to buy 106.25 square feet of wallpaper. This is area so you would do length times height. 8.5x12.5
Answer:
Step-by-step explanation:
Refraction, rotation and transformation are rigid motions,
so, they produce congruent figures.
Dilation does not preserve side length, so it is not a congruence transformation.
