Afunction, f(x), represents the distance, in miles, that sarah drives each hour, x. select the appropriate domain for this situation. a. the set of all positive integers. b. the set of all real numbers. c. the set of all real numbers greater than or equal to zero. d. the set of all integers.

21 i watched a 3 hr vid explaining it

step-by-step explanation:

du what else would it be

brainliest

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! : )
