Question: Let I = int _ 0 ^ 4 f ( x ) dx , where f is the function whose graph is shown. (

Let I=\int_0^4 f(x)dx, where f is the function whose graph is shown.
(a) Use the graph to find L_(2),R_(2) and M_(2).
L_(2)=
R_(2)=
M_(2)=
(b) Are these underestimates or overestimates of I ?
L_(2) is an underestimate.
L_(2) is an overestimate.
R_(2) is an underestimate.
R_(2) is an overestimate.
M_(2) is an underestimate.
M_(2) is an overestimate.
(c) Use the graph to find T_(2).
T_(2)=
How does it compare with I ?
T_(2)=,I
Let I = \ int _ 0 ^ 4 f ( x ) dx , where f is the
