1.Define what it means to say that lim x→2 f(x)=5
2.Define what it means to say that lim x→0 g(x)=k
3.A wrong statment about limits. Show by example that the following statement is wrong.
The number L is the limit of f(x) as x approaches x0 if f (x ) gets closer to L as x approaches x0.
Explain why the function in your example does not have the given value of Las a limit as x →x0.
以上是要寫出證明題!請教大家如何求出來 !!
謝謝!!
