The graph y=arctanx is transformed to y= aarctan(b(x-c))+d by a horizontal compression of 1/4 and a translation of π/3 units to the left. the new equation is: y=4arctan(x-π/3)
y=arctan(1/4(x+ π/3))
y=arctan(4(x-π/3))
y=arctan(4(x+ π/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.
