WebSal solves a few examples where the graphs of two functions are given and we're asked to find the limit of an expression that combines the two functions. For example, the limit at 0 of the product of the functions. Sort by: Top Voted. ... All right, we have graphical depictions of the graphs y equals f of x and y equals h of x. And we know ... WebA limit is defined as a number approached by the function as an independent function’s variable approaches a particular value. For instance, for a function f (x) = 4x, you can say that “The limit of f (x) as x approaches 2 is 8”. Symbolically, it is written as; lim x → 2 ( 4 x) = 4 × 2 = 8. Continuity is another popular topic in calculus.
