For a continuous function F on ( − 7 , 7 ), its derivative graph is constant at -1 on ( − 4 , − 1 ), is nonconstant on the other displayed intervals, and F ′ is undefined exactly at x = − 4 , − 1 , 4

Question

For a continuous function F on ( − 7 , 7 ), its derivative graph is constant at -1 on ( − 4 , − 1 ), is nonconstant on the other displayed intervals, and F ′ is undefined exactly at x = − 4 , − 1 , 4 . At how many points does F ′ ( x ) not exist?

TestHub · Accepted Answer

The graph states that F ′ is undefined at − 4 , − 1 , 4 , hence at 3 points.
