Show all necessary work. 1.) 4.) ) 0 tan 5.) cos 0 sin 3.) ) For the following function, does the Intermediate Value Theorem guarantee the eistence of a point between and 4 such that f(c) = 0? If so, find it. You may use your calculator. f() = ) The origins of calculus dealt with generalizing the idea of the slope of a line to other functions. Use the idea of the secant line and the iting process to eplain how this was done. Use complete sentences and proper grammar. Draw a picture if necessary for your eplanation to make sense. 8.) The graph below is the graph of f(). Each tick mark on the aes represents one unit. Answer the questions below. a.) What is f ( )? b.) What is f ( )? c.) Is f continuous at = -1? Why or why not? If not, is it removable or nonremovable? d.) What is f ( )? e.) What is f ( )? f.) Is f continuous at = 3? Why or why not? If not, is it removable or nonremovable?

Use linear approimations to find an estimate for Be sure to identify the function you used, what your "nice" number is, and the linear function you construct to find the approimation. 5.) Below you see three graphs. One of them is the function, f(), one is the derivative of f, and one of them is the second derivative of f (not necessarily in that order). They relate to the position of a particle in space where is time.

The top of the tank has a diameter of 8 feet and the tank is 10 feet tall. If water flows out of the tank at a rate of 1 cubic foot per hour, what is the rate of change of the depth when the water is 4 feet deep?

While Larry is on the ladder, his buddy, Bubba, starts backing up the truck, pushing the base of the ladder toward the building.

Suppose you are measuring a tin can and have a possible error of ±0.1 cm in any linear measure (radius, height, etc.). Given that the volume of a right circular cylinder is V = πr h, find the possible error in volume if the radius is measured to be 3 cm and the height 6 cm. Test #4 1.)
