What is a limit?

• a limit is a value equal to the area under the graph of a function for some interval or a new function, the derivative of which is the original function

• a limit is a instantaneous rate of change of a function with respect to one of its variables.

•  a limit is the value that a function (or sequence) approaches as the input approaches some value.

• all of the choices are correct
