X-CO, y -co and as x, y →-00 a. c. c. c. 6 2. Which polynomial function would have the end behaviour of as x 0, y co? a. f(x) = 7x' - 8x* - 2x + x + 3x-2 f(x) - -6x +37° +X-11 b. f(x)-4x2 + 3x* - 6x + 2x+8 d. f(x) = x - 9 3. The degree of the polynomial function y = x(x - 1)*(x + 1)' is 3 b. 4 5 d. 4. Given a function f(x) with the function values f(1) = 0, 62) - 64, 6-1)--24, and 10) --20, which value of x is a factor of the function? x=1 b. x=2 x-1 x=0 5.
