Answer 1

Ok, lets do the question 1 first.

Answer 2

inflection point is an x-value that makes f''(x)=0, so the f'(x) doesn't tell us anything about the inflection points.

So you can eliminate C, and it should be a critical point/number.
A critical number is when f'(x)=0. When is this the case, when x=1, or x=0?

Answer 3

When x=0

Answer 4

yes, correct, so your answer is...

Answer 5

A!

Answer 6

yes, the first option.

Answer 7

now, question #2 ...

Answer 8

Thanks an okay

Answer 9

See where x=-2.25 and x=-1.75 are on your graph?

Answer 10

Yes

Answer 11

this part of the graph you can take alone (and ignore the rest of the graph) to tell me the approximate slope at x=-2.

Answer 12

Don't they land in the middle of a box? How can I find the approx. slope?

Answer 13

You can just visually tell me, if you refer to your options....

Answer 14

you have no function f(x) given in a form of an equation, i know, but you can take that piece from x=-1.75 to x=-2.25, and tell me what the slope of this whole peace is appaorximately

Answer 15

2

Answer 16

oops not an option

Answer 17

take a narrower space on the function at about x=-2, and try to picture what a tangent line would look like

Answer 18

I still can't really see it. I'm just doing rise/run to count the slope on the graph is this wrong. I'm not really understanding it

Answer 19

it is correct, but you are taking a too wide interval....

i can't copy your picture..... wanted to show something but my extention for copying it isn't there...
