Run from Slope and Rise Suppose that f is a linear function with slope 3.4 and that f(1)6. What value of x gives f(x)=0?
Revenue The table shows the monthly revenue y (in thousands of dollars) of a landscaping business for each month of the year 2016, with x=1 representing January. A mathematical model that represents these data is fx1.97x+26.30.505x21.47x+6.3. (a) Use a graphing utility to graph the model. What is the domain of each part of the piecewise-defined function? How can you tell? (b) Find f5 and f11 and interpret your results in the context of the problem. (c) How do the values obtained from the model in part b compare with the actual data values?
Arboriculture The growth of a red oak tree is approximated by the function G=0.003t3+0.137t2+0.458t0.839,2t34 where G is the height of the tree (in feet) and t is its age (in years). (a) Use a graphing utility to graph the function. (b) Estimate the age of the tree when it is growing most rapidly. This point is called the point of diminishing returns because the increase in size will be less with each additional year. (c) Using calculus, the point of diminishing returns can be found by finding the vertex of the parabola y=0.009t2+0.274t+0.458. Find the vertex of this parabola. (d) Compare your results from parts (b) and (c).

Swimming Laps Miyuki practices swimming laps with her team. The function y=f(t) graphed below gives her distance in meters from the starting edge of the pool t seconds after she starts her laps. Describe in words Miyukis swim practice. What is her average speed for the first 30 s? Graph the function y=1.2f(t). How is the graph of the new function related to the graph of the original function? What is Miyukis new average speed for the first 30 s?
