For a certain car, the amount of gasoline, in gallons, remaining in the tank is modeled by the function G defined by G(t) = 18e
• Where t is measured in hours of driving. At t = 3.5, what is the rate of change of the amount of
gasoline remaining in the tank, in gallons per hour?
(a)
-1.788
(b)
-0.099
(c)
7.249
(D)
8.938

answer is:

1.75 pounds

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! : )
