Question

Here's a question: Identify each curve as f, f′, and f″

Answer 1

wheres the curve lol?

Answer 2

here is what you need to know

the zeros for f'(x) are the max and min of f(x)

the zeros of f"(x) are the max and mins of f'(x)

Answer 3

yup^^^

Answer 4

oops

the zeros of f"(x) will be the points of inflexion of f(x)

Answer 5

hope that helps...

Answer 6

sorry, not quite, where do I start?

Answer 7

ok... look for a line that cuts the x-axis... and directly above it is a maximum or minimum..... of another line

and look for a line that cuts the x-axis... and and directly above its is a max or min... and cuts another line where the concavity changes... point of inflexion... this will be f"(x)

the 1st solution is f'(x)

Answer 8

oh okay, thank you!
