Arthur has decided to start saving for a new computer. His money is currently in a piggy bank at home, modeled by the function s(x) = 85. He was told that he could do the laundry for the house and his allowance would be a(x) = 10(x - 1), where x is measured in weeks. Explain to Arthur how he can create a function that combines the two, and describe any simplification that can be done.

A clock is hung on a wall so that the bottom of the clock is exactly 75 inches above the ground. The minute hand (the longest hand) is 7 inches long and touches the edge of the clock. Write a function h(t)that describes the height of the tip of the minute hand above the ground at any time, t.  For ease, assume the scenario begins at noon. Recall: it takes 60 minutes for the minute hand to make a complete revolution around the clock.

.034x The assets (in billions of dollars) for a financial firm can be approximated by the function A(x) = 319e where x = 7 corresponds to the year 2007. Find the assets in each of the following years. (a) 2011 (b) 2015 (c) 2017 (a) Which of the following describes how to find the assets in 2011 using the given information? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal.) .034x O A. To find the assets in 2011, find the intersection point of the graphs y = 319e and y = 2011 are represented by the y-coordinate. O B. To find the assets in 2011, substitute for x and evaluate to find A(x). The assets in

Consider the graph of the function f(x) = x3. What would the graph look like if it was shifted down 3 units? What about to the left 2 units? Reflected on the x axis? Draw the graph that would make this change.
