Provide an appropriate response.Use the max-min inequality to find upper and lower bounds for
and
. Add these to arrive at an estimate of
.
What will be an ideal response?
If f(x) = on [1, 2], then max f = 1 and min f =
.
So min f ? (2 - 1) ? dx ? max f ? (2 - 1) or
?
dx ? 1.
If f(x) = on [2, 3], then max f =
and min f =
.
So min f ? (3 - 2) ? dx ? max f ? (3 - 2) or
?
dx ?
.
So +
?
dx ? 1 +
or
?
dx ?
