Question

Use the graph of f "(x) below to state x-coordinates of the inflection points for the graph of f(x)

a.0 only
b.4 only
c.0 and 4
d.2 only

Answer 1

what are the roots shown?

Answer 2

4 and 0

Answer 3

does the graph pass through the x-axis at these points? or just touch the x axis and turn around?

Answer 4

it passes through, picture is up top by the way

Answer 5

Yes I can see the picture. I'm asking to help you do problems like this on your own. Since f '' changes sign as we pass through either x = 0 or x = 4, this means there are 2 inflection points at x = 0 and x = 4

if f '' didn't change sign as you pass through a root, then it's not an inflection point

Answer 6

okay thank you very much

Answer 7

you're welcome
