The graph of a function fis given. Use the graph to estimate the following. (Enter your answers using interval notation.) (a) The domain and range of f. o range (b) The intervals on which fis increasing and on which f is decreasing. decreasing The manager of a furniture factory finds that it costs $2200 to produce 100 chairs in one day and $4400 to produce 300 chairs in one day. (a) Assuming that the relationship between cost and the number of chairs produced is linear, find a linear function C that models the cost of producing x chairs in one day. C(x) = (b) Draw a graph of C.
