precalculus functions of a graph (the picture is huge but keep scrolling down please)

[cats]

ok, so I don't understand what question number 14 is asking (14. solve f(x)=g(x) for x using the graph). I think maybe it wants me to set set points that are on lines g and f equal to each other, but I'm not sure because then the problem will have two answers. Please help, and sorry if the image isn't clear.

I believe your interpretation of problem #14 is correct. It is simply asking you to give the x-coordinate(s) at which the two functions are equal. The algebraic notation, that is, f(x)=g(x) can be graphically represented by the point(s) at which the two functions intersect. Sometimes there will be one answer, but any number of answers is perfectly fine. Some functions intersect at zero points (or really we'd say they don't intersect) and some functions intersect at infinitely many points.
