Find the domain of the graphed function.
2 answers:
For every point on the curve, imagine drawing a vertical line until that vertical line reaches the x axis.
Doing this will essentially shade the x axis number line from x = -4 to x = 2
The graph shows points in which the x coordinate is as small as -4 or as large as 2, or anything in between
Domain:
Answer: Choice B
note: the domain is the set of allowed inputs or x values

Karen has a base salary that is $2100 and does not depends on how many copies she sells.
Additional to the base salary, she gets $50 for each copy she sells, so we can write this additional salary as 50*N, being N the number of copies she sells.
Then, we can write the total pay P as:
Then, if N=22, we can calculate the total pay as:
Answer:
The equation relating P and N is P=2100+50N.
The total pay when she sells 22 copies is $3,200.
