Answer 1

will it be where x = 4?

Answer 2

you're given the graph of f '

what does f ' say about f itself ?

Answer 3

critical points are where f ' equals 0

Answer 4

and critical points are possible extrema

Answer 5

F ' ALSO SHOWS SLOPE

Answer 6

sorry caps lock was on

Answer 7

exactly, f ' tells us the slope of the tangent lines of f

translation: we can figure out where f is increasing or decreasing based on the graph of f '

Answer 8

where is f increasing? where is f decreasing?

Answer 9

f is increasing on intervals [-2,2] amd [4,6]

Answer 10

careful, this isn't the graph of f
