Name the complex expression to form a conjugate pair.

Note

Problems 1–2

You learned about complex conjugate pairs in Unit 2.

$7 - 4 i$

$7 + 4 i$

$1 + i$

$1 - i$

Determine the possible maximum degree from the graph.

Note

Problems 3–4

Recall, C: cross-through (multiplicity 1), B: bounce (multiplicity 2), S: snake (multiplicity 3)

2 + 1 + 2 + 1 = 6

3 + 2 + 1 + 3 = 9
