Austin is comparing the prices of two truck rental companies. company a charges $4 per hour and an additional $70 as service charges. company b charges $5 per hour and an additional $60 as service charges. part a: write an equation to represent each company's total charges for renting a truck for a certain number of hours. for both equations (one for company a and one for company b), define the variable used. (4 points) part b: which company would charge less for renting a truck for 6 hours? justify your answer. (3 points) part c: how much money is saved by using the services of company b instead of company a to rent a truck for 7 hours? (3 points)

answer: f true

step-by-step explanation:

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! : )
