Dion grated 1/2 cup of cheese for a pasta dish. the recipe calls for 2/3 cup. how much more cheese does dion need to grate? which equation could dion have written to correctly solve his problem? circle all that apply.

a. 2/3 = 1/2+1/3
b.2/3 - 1/2 = 4/6 = 3/6
c.2/3 - 1/2 = 8/12 - 6/12
d.2/3 + 1/2= 4/6 + 3/6

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! : )
