(1 point) In this problem you will calculate the area between f(x) = x2 and the x-axis over the interval [3,12] using a limit of right-endpoint Riemann sums: Area = lim ( f(xxAx bir (3 forwar). Express the following quantities in terms of n, the number of rectangles in the Riemann sum, and k, the index for the rectangles in the Riemann sum. a. We start by subdividing [3, 12) into n equal width subintervals [x0, x1], [x1, x2),..., [Xn-1,...

Evaluate the integral [c F.dr. F(x, y) = (x + y) i + (3x - cos y) j where is the boundary of the region that is inside the square with vertices (0,0), (4,0),(4,4), (0,4) but is outside the rectangle with vertices (1, 1), (3,1),(3,2), (1,2). Assume that C is oriented so that the region R is on the left when the boundary is traversed in the direction of its orientation.

For the function f(x,y) = 4y2 + 3x², find f(3. - 4), (-4,4), f(-1,-2), and f(0,7). f(3,-4)= (Type an exact answer, using radicals as needed.) f(-4,4)= (Type an exact answer, using radicals as needed.) f(-1, - 2) = (Type an exact answer, using radicals as needed.) f(0.7) = (Type an exact answer, using radicals as needed.)
Let f(x) = 3x – 6 and g(x) = 6x + 5. Write a formula for each of the following functions and then simplify e. fg= Preview f. ff= Preview
Consider the function f(x) = x3 + 3x² - 9x +1. (a) Identify all critical points of f(x). (Providing the -values will be sufficient. Hint: They will be integers.) (b) Use your answer from (a) to identify the absolute maximum value (global max) and absolute minimum value (global min) of f(x) over the x-interval (-2,2].
