Answer:
f(x) = x³ − 5x² − 16x + 80
Step-by-step explanation:
The degree is 3, so there are exactly 3 zeros.
The zeros are -4, 4, and 5.
f(x) = (x + 4) (x − 4) (x − 5)
f(x) = (x² − 16) (x − 5)
f(x) = x³ − 5x² − 16x + 80
P(<em>Z</em> ≥ <em>z</em>) = 1 - P(<em>Z</em> ≤ <em>z</em>) = 0.06
==> P(<em>Z</em> ≤ <em>z</em>) = 0.94
==> <em>z</em> ≈ 1.7507
