Answer 1

A)

Answer 2

B)

Answer 3

C)

Answer 4

D)

Answer 5

@electrokid can u help?

Answer 6

Critical point are where the gradient is zero, so it is instantaneously flat at -1,0,1.

Answer 7

okay so its A?

Answer 8

No....A has only one critical point at x=0.

Answer 9

okay so its D

Answer 10

Sorry no again! D has only the one critical point at x=0 again. A quadratic graph has only one critical point since it only changes direction once. Infact, that's perhaps a better way to think about it: a critical point is where the curve changes direction.

Answer 11

ohhh okay got it

Answer 12

so its gotta be B

Answer 13
