    Graph
In summary, the conversation discusses finding the domain and range of a graph and the values of functions at specific points on the graph. It is clarified that the functions a-d are not to be graphed, but rather the values are to be read from the existing graph. The values given for each function are 0, -1, 0, and -2 respectively.

Homework Equations





The Attempt at a Solution



I got the DOmain and Range of the graph, but then it says to do the same for the functions a-d. If you graph them then they are all straight lines so there's really only a domain.

But when I checked at the back of the book, the answers came to be

A)0
B)-1
C)0
D)-2

I'm sure I'm missing something. Any help is appreciated. Thank you.

You are misunderstanding that part of the problem. They are just asking you to use the graph to read off the values of the function f(x) at each of the indicated values of x .
