Bracketing is a bit off. I guess you mean (√(x+4) - 2]/x )(√(x+4) + 2)/(√(x+4) +2)lionely said:(√(x+4) - 2]/x )(√(x+4) + 2]/√(x+4) +2]
I don't. Please post your working.and then put in 0 I get 0..
No, not all limits can be solved algebraically. Some limits may involve indeterminate forms such as 0/0 or infinity/infinity, which cannot be solved algebraically.
Indeterminate forms in limits refer to situations where the value of the limit cannot be determined using direct substitution. These include forms such as 0/0, infinity/infinity, and infinity - infinity.
Limits can be solved algebraically by using limit laws and algebraic manipulation to simplify the expression until a direct substitution can be made. If the limit involves an indeterminate form, additional techniques such as L'Hôpital's rule may be used.
Yes, there are limits that cannot be solved algebraically or numerically. These are known as non-computable limits and require advanced mathematical techniques to determine their value.
Yes, limits can also be solved using a graph, particularly for limits involving piecewise functions or discontinuous functions. The graph can help to visualize the behavior of the function and determine the limit at a given point.
