State the practical meaning of the slope and y-intercept for the situation described. The cost, in dollars, of retaining the services of a computer repairman in Anchorville is given by C = 48x + 18, where x is the number of hours worked. a. 48 signifies the hourly rate, and 18 signifies the overhead charge. c. 18 signifies the hourly rate, and 48 signifies the overhead charge. b. -48 signifies the hourly rate, and 18 signifies the travel cost. d. 66 signifies the cost for an on-site inspection.

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.
