Let R be the region bounded by the y axis and the graphs of y=4x-x^3+1 and y=3/4x. Find the perimeter of R.?

How do you find the sides of this to get the perimeter?

If you do use the arc length formula then what would the dy/dx be for this problem since there are two curves? and it is (3/4)x

The region is more/less triangular with 2 straight sides. You only need the arc length of the cubic between the intersection of y=(3/4)x & the cubic up to the y-axis. OK?
