Finding Limits From a Graph
As X gets closer to (), f(x) values get closer to ()
limit as x approaches () of f(x) = ()
it doesn’t matter what actually happens AT the Y-value, the only thing that’s important is what happens when you get CLOSE TO the Y-value. that’s the definition of LIMIT.
if the limit approaches a different number on one side we say the limit does not exist LIMIT DNO.
The Golden Ratio (golden mean, divine proportion) is the ratio of two quantities (equivalent to approximately 1 : 1.6180339887). It occurs when the ratio of the sum to the larger number equals the ratio of the larger number to the smaller number.
