@jim_thompson5910 would you be able to explain this? please!

Answer 3

@jim_thompson5910

Answer 4

what is the highest y value

Answer 5

and for what x does that y occur

Answer 6

oh that isn't f
it is f' in drawing

Answer 7

first of all the endpoints are at x=-2 and x=6
and then the critical numbers will occur at the x-intercepts of the f' function there

Answer 8

so we need to consider the following x values:
x=-2,x=2,x=4,x=6
the absolute max will occur at at least one of these

Answer 9

oops x=5 not 4

Answer 10

okay got it so far

Answer 11

thinking on the other part
like do you have any ideas

Answer 12

i looked though my lesson and couldnt find anything that would help me solve this :/ im looking again

Answer 13

I can tell you I think it isn't 2 or 5
because we have this:

like f'<0 from x=-2 to 4 so we know f is decreasing from x=-2 to 4
and f'>0 from x=4 to 6 so we know f is increasing from x=4 to 6
