A carpenter charges $30 per hour for up to eight hours each day and increases this rate by 50% for additional hours. the carpent
er 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
d. if a $20 trip carve is added, the new x-intercept will be (20,0)
