Acountry produced 3.5 billion gal of fuel ethanol in 2005. the production of corn-based ethanol has increased exponentially from only 1.1 billion gal in 1998. the
following function can be used to model this growth.
c(t) = 1.0647(1.1597), where t is the number of years since 1998
predict the number of gallons that will be produced in 2007 and 2009.
in 2007, billion gallons will be produced.
(round to one decimal place as needed.)

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! : )
