Limit Questions Flashcards
What are Limits importance in calculus?
Defining integrals, derivatives and continuity, concerning behaviour of the function at a particular point.
What are limits?
Unique real numbers in real-valued function; if you consider a real-valued function f and the real number c, limit defines as lim x—>c f(x) =L
What are the two limits a function can approach?
One where the variable approaches its limit through values larger than the limit and the other where the variable approaches its limit through values smaller than the limit.
Example of an independent variable and dependent variable.
Age in years is not affected by diet, exercise etc.
A test score can be dependent on sleep, study time etc.
What is an example of a limit with relation to the function f (X) = x + 2?
The limit of f at x =3 is the value f approaches as we get closer to x = 3, in graph form being the y value we approach when we look at the graph of f and get closer to the point of the graph where x =3/
Mathematically what would limit of f (x) = x + 2 look like in a graph?
A P1 of (1 , 3) moves across a graph until close to x=3, of which, y value(the value of the functions) gets really close to 5, thus limit of x=3 is 5
