Acarpenter charges $30 per hour for up to eight hours each day and increases this rate by 50% for additional hours. the carpenter will not work more than ten hours per day. if this daily cost function is modeled by y = f(x) and graphed, which statement is not correct?
a) f(0) = 0, f(8) = 240, and f(10) = 330.
b) the domain is [0, 10] and the range is [0, 330].
c) the graph is increasing on the interval (8, 10) with a slope of 45.
