If you need to expand, you multiply all the terms:

x^2 * x^2 = x^4
x^2 * -4 = -4x^2
4 * x^2 = 4x^2
4 * -4 = -16

And then combine:

x^4 - 4x^2 + 4x^2 - 16

Which becomes:

x^2 - 16

Which of the following is the graph of the piecewise function
trapecia [35]

By analyzing the piecewise function, we conclude that the first graph is the correct one,

<h3>Which of the following is the graph of the piecewise function?</h3>

The first part of the piecewise function is:

f(x) = √(-x - 2) for x ≤ -2

This parts ends at:

f(-2) = 0

With that, we can discard the last two graphs.

Now, the second part is a rational function with a negative coefficient.

Because of that sign, when x is positive, the function tends to negative infinite near in the asymptote, while when x is negative, the function tends to positive infinite in the asymptote.

Because of that, we conclude that the correct option is the first graph.
