What are the domain and range of the function {(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)}?

a.

domain: {3, 1, 9, 4}; range: {5, 7, 11, 4, }

b.
domain: {5, 7, 11, 4, }; range: {3, 1, 9, 4}

c.
domain: {5, 7, 11, 4, –2}; range: {3, 1, –2, 9, 4}

d.

domain: {3, 1, –2, 9, 4}; range: {5, 7, 11, 4, –2}

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

The two square pyramids are similar. find the total volume of both pyramids if the ratio of their surface areas is 9/16

Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles. answer to the nearest integer.
