Question

Estimate the area under the graph of f(x)=7/x from x=1 to x=7 by using 6 approximating rectangular

Estimate with right endpoints=_____________________________
Estimate with left endpoints=___________________________

Answer 1

the intervals are all of width 1, so
right: 1(f(2)+f(3)+... + f(7))
left: 1(f(1)+f(2)+...+f(6))
so plug and chug

Answer 2

is this the simplified answer because when I simplify this I get 9f, which isn't the right answer

Answer 3

oh dear !

Answer 4

f is not a number
f(x) = 7/x
so,
f(1) = 7/1
f(2) = 7/2
and so on
If you are taking calculus, I find it incredible that you would make such a blunder.
