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)

2.6 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.

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?

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!!
