Limits & Continuity unit test
A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

Consider the differential equation dy/dx = xy², and let y = f(x) be the particular solution with f(0) = 1.
Write an equation for the line tangent to the graph of f at (0, 1), and use it to approximate f(0.5).
Use separation of variables to find the particular solution y = f(x).
State the largest open interval containing x = 0 on which the solution from part (b) is defined, and explain what limits it.
