A website sells popular books in hardcover, paperback, and digital form. The paperback version of a book sells for 12 dollars less than the hardcover version, and the digital version sells for half the price of the paperback copy. The website adds a finance charge equal to 1/10 of the price of the hardcover version to all purchases.

Which expressions represent the total cost of the digital version of a book if the hardcover price is h dollars?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
