No, its not. In a function, each x value has only one corresponding y value. In this relation, the x value 3 has corresponding values of both -1 and 5, which means it cant be a function.
Of course it's possible, because it means that sintheta=-2/5 which satisfies this -1<=sintheta<=1
Answer: B (130)
Explanation:
A trapezoidal Riemann sum can be found by multiplying the width (the change in x) of each sub interval by the average of the y values of the two points at either end of the section and then adding up all of the sun intervals. Therefore, the trapezoidal approximation would equal 0.5(40) + 1.5(50) + 1(35) to get the answer of 130.
