1. Pg. 136/140 Homework Study!! Not required, but the inverse wkst is good practice! #18Not 1 – 1, fails HLT #20Yes 1 – 1, passes VLT and HLT #22Yes 1 – 1, passes VLT and HLT #24Yes #26You graph it!! #28 #33f -1 (x) = (2x + 3)/(x – 1) #34f -1 (x) = (-x – 3)/(x – 2)

2. 2.4 Solving Linear Inequalities Solving Linear Inequalities Algebraically Solve algebraically:

3. 2.5 Solving Higher-order Inequalities Algebraically and Graphically Solve algebraically.

4. 2.6 Relations and Parametric Equations Circles Write the following equation of a circle in standard form and state the center and radius. Symmetry Determine the type of symmetry, if any, of the equations below.

5. 2.7 Inverse Functions Inverse Functions Show that f(x) = will have an inverse function. – Find the inverse function and state its domain and range. – Prove that the two are actually inverses. Show that g(x) = will have an inverse function. – Find the inverse function and state its domain and range. – Prove that the two are actually inverses. Will h(x) = x 3 – 2x will have an inverse function?

6. 2.4 – 2.7 Test Review Don’t forget – Word Problems!! – To flip inequalities when dividing by a negative – That if a zero is in the denominator of a sign pattern it is undefined (which means a parentheses must be used!) – To check both ways when algebraically proving an inverse – You will be deriving the quadratic formula!!
