The answer to (a)(b)(c) is 2,656
VXW is 68 degrees
You can use the alternate interior angles theorem to put XVW as 52 degrees and then add 52 and 60 up and subtract from 180 since every triangle has 180 degrees
You are right about the domain
it is all real values of x except 4
So about the range we must make x subject of the formular so we know the values of y in which g(x) is defined

u
The solution is where the two lines meet. From the the graph, it looks like
(1, -1)
