The amount of fuel remaining in a gas grill, y, is a function of the number of hours, x, that the grill has been used. This relationship can be expressed by this function: y = 10 - X.
Which of these represents reasonable domain and range of the function for this situation?
F
Domain: Os x S 10; Range: 0 sy s 10.
G Domain: Os x S 10; Range: All real numbers.
H Domain: All real numbers; Range: 0 sy s 10.
J Domain: All real numbers; Range: All real numbers.

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! : )
