Homework:
POW due Fri-Wed
Quiz on Rational Functions 10/10
Revisit HW 12
Notes: Starting Pollsters Dilemma on Friday, just finishing Rational Function unit
End Behavior
x to the power of an odd number will give an equation like this
X^any even number:
Example of an exponential function (y=4^x):
Rational Function Review:
Bottom power is bigger-HA=0
Top power is bigger-no HA
Power is same-ratio of leading coefficients is HA
Solving Equations and Inequalities
Algebraically
Technology
Graphing or Table
Intersection on calculator: split equation into two with y equalling both halves, calculate intersection or look at data table for the same Y value
Algebra: cross multiply if fraction=fraction then simplify. If not, multiply both by LCD, input answers back into the initial equation and eliminate the extraneous "solution".
