What is a limit in calculus?

Back

A limit is a value that a function approaches as the input approaches some value.

Front

How do you find the limit of a function as x approaches a specific value?

Back

To find the limit, you can substitute the value into the function, simplify, and check if the function approaches a specific value.

Front

What does it mean for a function to be continuous at a point?

Back

A function is continuous at a point if the limit as x approaches that point equals the function's value at that point.

Front

What is the significance of a hole in a graph?

Back

A hole in a graph indicates that the function is not defined at that point, often due to a removable discontinuity.

Front

What is the difference between a removable and a non-removable discontinuity?

Back

A removable discontinuity can be 'fixed' by redefining the function at that point, while a non-removable discontinuity cannot.

Front

What is the limit of a constant function?

Back

The limit of a constant function as x approaches any value is the constant itself.

Front

How do you determine the limit of a rational function?

Back

To determine the limit of a rational function, factor the numerator and denominator and simplify, then substitute the value.

Front

What is the limit of a function as x approaches infinity?

Back

The limit as x approaches infinity describes the behavior of the function as the input grows without bound.

Front

What is the Squeeze Theorem?

Back

The Squeeze Theorem states that if a function is squeezed between two other functions that have the same limit at a point, then it also has that limit.

Front

What is the definition of continuity in terms of limits?

Back

A function f(x) is continuous at x = a if: 1) f(a) is defined, 2) the limit of f(x) as x approaches a exists, and 3) the limit equals f(a).
