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.

I would think that the answer is C because her distance is always increasing as long as shes moving, it isn't asking for direction, so no matter if she goes forward then backwards then forwards again she has still traveled that distance, so I believe its C because you can't go negative distance, even if you go backwards

If your asking how much altogether for 12 performance the answer will be 98,496.

Answer: f(x) = -2x^3 +3x^2 +11x -6see attachedan infinite number. since the magnitude of the leading coefficient is not specified, it may be any negative number. (we have chosen the smallest magnitude integer that makes all coefficients be integers.)step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
