Answer:
(a) a function, but not one-to-one
Step-by-step explanation:
The graph is of a function if it passes the vertical line test: a vertical line intersects the graph in at most 1 point.
The function is one-to-one if it passes the horizontal line test: a horizontal line intersects the graph in at most 1 point.
__
Here, the graph consists of a series of non-overlapping horizontal lines. It passes the vertical line test (is a function), but a horizontal line can intersect the graph in an infinite number of points (is not one-to-one).
The graph is a function, but not one-to-one.

Answer:
c) $615
Step-by-step explanation:
The expression used to determine how much is the charge for the customer after the job is

where
h is the number of hours the job took
c is the number of cans of paint used during the job
In this problem:
c = 3 (the painter used 3 cans of paint)
h = 15 (the painter took 15 hours for the job)
So substituting these values into the equation for p, we find the total value that the painter charged for the job:

So, the correct answer is
c) $615
