Example items pre-calculus pre-ap, sem 1
a polynomial function of degree four is graphed as shown
2001
- 2001
400
-600
-1001
-1000+
based on this graph, which statement is true?
a
b.
f(x) has a total of four roots and three local extrema.
f(x) has a total of two roots and three local extrema.
f(x) has a total of two roots and five extrema.
f(x) has a total of four roots and five extrema.
the formula to calculate the level of sound intensity in decibels (db) is
2
b = 10 109
where ß is the number of decibels, i is the sound intensity in watts per square meter (w/m2) of
any sound, and i. = 10-12 w/m2, which is the intensity of the faintest sound audible to the
human ear. the pain threshold for the human ear is 120 db. what is the intensity, i, of this
sound?
b
10120 w/m2
1012 w/m2
10° w/m2
10-12 w/m2
