If f is increasing, continuous, positive, and concave up on an interval [a, b], and if Ln, Mn, Tn, and Rn are the left, midpoint, trapezoidal, and right sums for n subintervals, which of these is not true? a. Ln <= Mn <= Rn
b. Ln <= Tn <= Mn
c. Mn < (Ln+ Rn)/2
d. L2n > Ln

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
