1. Find the number of digits in the expansion of (2^120)(5^125) without any calculator or computer.

2. Find the coordinates of the two points that trisect the line segment with the endpoints (A(2,3) B(8,2).

l l = Absolute value

3. Give the function f(x) = x^3 - 2x, sketch y = f(lxl).

Sketch g(x) = lx^2 - 1l - lx^2 - 4l

Sketch the region in the plane to show all points (x,y)

such that lxl + lyl <= 2
