9: y=5(x-1)^2-3
standard form: y=5x^2-10x+2
10: y=3(x+3)^2+2
standard form: y=3x^2+18x+29
are they together life solving linear equations?
Answer:
<h2>4</h2>
Step-by-step explanation:
From first piece -6 < x ≤ 0.
From second piece 0 < x ≤ 4.
Therefore -6 < x ≤ 4 → x ∈ (-6, 4]
-7 ∉ (-6, 4]
-6 ∉ (-6, 4]
4 ∈ (-6, 4]
5 ∉ (-6, 4]
