If writing process is bothering you,

it's ok to write only correct answer in each question.

1. Let f (r, y) be a continuous function of two variables. If you take the definite integral of f (2, y) with respect to c, what is the result? O A function of r only A function of y only A function of both r and y A constant 2. True or false? If the graph of the integrable function g (2, y) lies above the ry-plane for all points (c, y), then the double integral of g(, y) over any rectangle is positive. True False 3.
