Rafael watches a football game every sunday. rafael did not watch any football game this sunday. it can be said that: a) rafael forgot about the game. b) rafael did not want to watch the game this sunday c) did not play football this sunday d) rafael changed his routine.

a) would be one of the most reasonable answers. Technically we cant determine if Rafael did not want to watch the game or if he changed his routine. We can only determine that he might have forgotten this Sunday.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
