If trapezoid ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A' lie?
Dmitrij [34]
A is the point (-4, 1)

i) reflection over the y-axis projects a point (a, b) to (-a, b):

(-4, 1) is projected to (4, 1), 

ii) reflection over the x axis projects a point (a, b) to (a, -b):

(4, 1) is projected to (4, -1),

iii) rotation 180 degrees: projects (a, b) to (-a, -b):

so (4, -1) is projected to (-4, 1)


Answer: A'(-4, 1)

The graph of g(x) is a reflection and translation of<br> f(x) = ³√x.
yaroslaw [1]

The function g(x) will be given as g(x) = – ∛(x – 1). Then the correct option is D.

The complete question is attached below.

<h3>What is a transformation of geometry?</h3>

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Reflection does not change the size and shape of the geometry.

Translation does not change the size and shape of the geometry.

The function f(x) is given below.

f(x) = ∛x

Then the function of the g(x) will be

g(x) = – ∛(x – 1)

Then the correct option is D.

More about the transformation of geometry link is given below.

The third and last options are the answers.
The graph is shifted to the right by some number. The coordinates aren't numbered, so it could be literally anything. To shift to the right, the equation will be |x-y| where y is any number.
