Given that p(-3) = 0, p(-1) = 0, and p(5) = 0, which expression could be p(x)? A) x3–x2–17x –15
B) x3+ x2–17x + 15
C) x3–3x2–13x + 15
D) x3–9x2+ 23x –15

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
