You order inspections of 100 nearby bridges, and the report indicates that 30 bridges have deck deterioration, and 40 bridges have column deterioration. Ten of the bridges have both column and deck deterioration. a) How many bridges have no deck deterioration?
b) How many bridges have deck deterioration but no column deterioration?
c) How many bridges have deck or column deterioration (or both)?
d) How many have neither deck nor column deterioration?

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
