1.A whale is at the surface of the ocean to breathe. What is the whale's elevation? 2. The whale swims down 300 feet to feed. What is the whale's elevation now?

3. The whale swims down 150 more feet more. What is the whale's elevation now?

4.Plot each of the three elevations as a point on a vertical number line. Label each point with its numeric value.

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

What are the domain and range of the function f(x)=2^x+1

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
