How do I go about this?

1. The position of an object (measured in feet) moving on a line is given by the function s(() = 18 - 1+ 5, Find the average velocity of the object on the time interval (measured in seconds) [2, 6]. Include the proper units in your answer. 2. Find the average rate of change for the function f(x) = cos(x) on the x-interval ;. "|. No calculators and simplify your answer, which means no fractions in your fraction.3. Find the slope of the secant line for the function g(x) = x3 + 2x -5 on the x-interval [-1,3]. 4. Given the function f(x) = x3 - x + 1, find the following: a. Fill in the table - Please feel free to use a calculator, when necessary. x-interval: [1,2] [1,1.5] [1,1.25] [1,1.1] (1,1.01] b. Make an educated guess about the slope of the tangent line at x = 1. mean = c. Below is a graph of f(x) = x - x + 1. Draw the secant lines for the x-intervals [ 1,2], [ 1, 1.51. and [1,1.25] from part a. Then draw the tangent line at x = 1 to verify that it agrees with your answer from part b. 8 -7- -3 05 075 1.25 1/5 175 2
