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. d) if a $20 trip charge is added, the new x-intercept will be (20, 0).

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
