Chapter 1.1 -1.10 Test Answers

Answers to a test that covers basic functions. This includes the "families of functions" (absolute value, square root, square, cubic, reciprocal, etc.) and how algebraic changes of the function has the effect of shifting, reflecting or distorting the graph of the basic function. The test also covers domain, range, one-to-one (injective) functions, and inverse functions.

Welcome

If you are getting ready for calculus, at some point you may need to take a "Math Readiness Test" to qualify to enroll.  This blog and video podcast is just for you.  I will post a number of problems that I have been asked to solve that could be on this test.  It includes algebra, geometry, trigonometry, mathematical modeling, "word problems", logarithms, discrete mathematics, matrices, sequences and any sort of problem anyone starting Calculus should be familiar with.

Good luck!
