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 charge is added, the new x-intercept will be (20, 0).

Answer:

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

This statement is false. The original graph started at (0,0), the x-intercept. Adding a 20$ trip charge moves the graph up 20 so there would not be an x-intercept.
