Question

question is inside please help :)

Answer 1

ok so i have never been good at graphs. :( i dont know how to work these. i do understand the fundamental theorem of calculus. but the graphs throw me off. I'd like to be able to work these on my own, can someone teach me how to approach these?

Answer 2

Ok, what does the Fundamental Theorem of Calculus states?

Answer 3

But what is the problem?

Answer 4

ahh to find f(4)

Answer 5

without the graphs these i can work with, with graphs it just gets all fuzzy. And I don't know what to do.

Answer 6

I think that: \[\int_1^4 f'(x) dx = f(4) - f(1)
\]

Answer 7

So 6.2 = f(4) - 3

Answer 8

is it clear?

Answer 9

yeah up to here i understand :)

Answer 10

solve the last equation for f(4) and you got it.

Answer 11

oh. wow. so i completely over thought this =O i was setting up right, but i got all nervous and stopped. wow. i feel embarrassed now.

Answer 12

I sometimes over thought problems. Don't worry =P
