Given a graph for the transformation of f(x) in the format g(x)=f(kx), determine the k value

k=-1/3

k=1/3

k=-3

k=3

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.
