Study Guide Ch 6 Test
A. Simplify Exponents – Rational Exponent form vs Radical form. Rationalize!
B. Function Operations –
C. Domain and Range - ≥ vs ≠, it is the DEFINED x and y values for the function.
D. Composite Functions- Plug one into the other. Check domain of the original functions too
Use the functions from Section B above. Find the domain and range of 6-8.
E. Graphing Radicals – Find starting point using horizontal/vertical translation then plug in a point to get the “curve”
F. Solving Radical Equations – isolate the radical or get one radical on each side. Check for extraneous solutions
G. Inverse Functions – Switch x and y then solve. f(f-1(x)) = x
Find the inverse
