Answer:
your answer is point g and h
X⁴ - y⁴
x⁴ - x²y² + x²y² - y⁴
x²(x²) - x²(y²) + y²(x²) - y²(y²)
x²(x² - y²) + y²(x² - y²)
(x² + y²)(x² - y²)
The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).
The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].
The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].
Overall, this function has a domain of
[-4, 1) U [-1, 2] U (2, 5]
(where U means "union" in the set-theoretic notion)
But this also simplifies to the interval [-4, 5].
These correspond to the <u>first</u> and <u>last</u> choices.
It will become 61
because anything above 0.5 rounds up
