When it is raining outside, you tend to stay in and watch TV. The number of hours of TV that you watch in a given week is twice the number of rainy days in that week. In the equation below, the number of hours of TV you watch in a week, and xxx is the number of rainy days in that week. The relationship between these two variables can be expressed by the following equation:
y=2x
Identify the dependent and independent variables.

Dependent variable Independent variable
The number of rainy days in a week
The number of hours of TV you watch in a week

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! : )
