## Grade 9 Math Exam Practice Test With Answers

This is a required course, designed for students who are planning to attend college or pursue a technical post-secondary career. The course emphasizes facility with symbolic expressions and forms, alongside graphical and tabular representations. It moves beyond the linear and quadratic forms learned in Algebra 1, to several other families of functions that extend those fundamental concepts. It also builds upon concepts of scaling and transformation from Geometry.

Students will study polynomial, rational, exponential, logarithmic, trigonometric, and discrete families; and will build functions by combination and composition, investigating both their abstract properties and the use of functions as tools for modeling real-world situations.

•Mathematical thinking is about depth not speed. 3) TEXTBOOK: Holt McDougal & Larson Algebra 2. We have a *homework done by due date. *eye contact to.

Yesterday we developed the definition of inverse functions using only linear functions and graphed to demonstrate the symmetry. Time to see what we have learned:. But after my prodding that they somehow verify the inverse relationship, we soon verified that f g x did not produce the result we desired. The second example was then complete easily. But what about that third problem?

They sure seem like inverses. One student offered his proof for the pair:. And a few numerical examples help show this:. Students in my class have not been exposed to a formal definition of the square root function, and this led to a nice discussion of absolute value, and the need to restrict the domain in order to consider inverses. Planting seeds for algebra 2, which many of my students will take next semester, is always a bonus.
