Final Answer:

The equation of the graph that represents the reflection of
\(y = -|x - 1| - 1\) about the origin is
\(y = |x + 1| - 1\).

Step-by-step explanation:

To find the equation of the graph that represents the reflection of
\(y = -|x - 1| - 1\) about the origin, we'll determine how the graph of the function
\(y = -|x - 1| - 1\)changes due to the reflection across the origin.

The graph
\(y = -|x - 1| - 1\)is a reflection of the absolute value function
\(y = |x|\) over the x-axis, shifted one unit to the right and down by one unit. When reflecting a graph about the origin, both the x and y values change signs.

For the original equation
\(y = -|x - 1| - 1\),to reflect it across the origin, the negative sign before the absolute value is reversed to a positive sign. Hence,
\(y = |x + 1| - 1\) represents the reflected graph.

The transformation from
\(y = -|x - 1| - 1\) to \(y = |x + 1| - 1\)involves replacing
\(x\) with \(-x\) to reflect the graph over the y-axis and changing the constant term from
\(-1\) to \(1\) to reflect it over the x-axis. This results in the equation
\(y = |x + 1| - 1\), representing the graph of the function reflected about the origin.

Answer:

f(x) = |x + 1| + 1

Step-by-step explanation:

A reflection over the y-axis followed by a reflection over x-axis is equivalent to a reflection about origin.

f(x) = -|x-1| -1

reflection over the x-axis:

-f(x) = (-1)*(-|x-1| -1) = |x-1| +1

reflection over the y-axis of the previous function:

-f(-x) = |-x-1| +1 = |x + 1| + 1

which is the reflection of f(x) about the origin
