How many points off would I get if I got just the h’’ part wrong for part c?

[@kangfraddy6013]

for part c if i said undefined instead of 0 would i still get the point for g’’(6)

[@miguelito0716]

I said this and realized my mistake, I don’t think you would get the point unfortunately because it would be 0

[@ordinaryerod3553]

would you include endpoints on b?

[@RCStudiosDevelopment]

thats what i was wondering, i put both the endpoints

[@RCStudiosDevelopment]

nevermind its only x = 6, 4 since the interval is between 0 and 6 inclusive, so the -6 endpoint wouldnt count

[@ordinaryerod3553]

@@RCStudiosDevelopment 😔 hopefully it isn’t too many points off

[@vibezone2040]

I said h'' was undefined 💀

[@Accuracy321]

easiest frq,9/9

[@benrobs5553]

questions 1 and 3 were sooooo much easier

[@sparshjain3360]

For part B, I think you forgot to include the endpoints, as they would also be critical points

[@vishtoxic5928]

Yeah I included the points in my frq. I think the college board accepts both

[@and-qw8jk]

No that is for the candidates test

[@Han-D4ror2]

those aint critical points… critical points are where f’(x) = 0

[@sparshjain3360]

@@Han-D4ror2 nope. Not true. Go study calc again

[@Han-D4ror2]

⁠@@sparshjain3360endpoints of g(x) would be considered critical points. however, the graph shows g’(x) and it is on a closed interval. g’(-6) and g’(7) are both defined and are not 0, therefore they are not critical points.
dont be an ass if you dont know what youre talking about
