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).

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.

Step-by-step explanation:

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
