Compare and contrast the following piecewise defined functions.

Question illustration
Answer:

Both functions have the same domain—all real numbers except 0. Both are made up of linear and quadratic pieces, but f has a jump discontinuity while g has a point discontinuity. The range of f is y > 1, while the range of g is all real numbers except 2.
