The limit of a constant function is always equal to the constant. What are the different laws of limits? The different laws of limits are: Sum Law Difference Law Product Law Quotient Law Constant Multiple Law Power Law Can we break up the limits to get the solution?
Limit of a Function: This problem involves finding the limit of a function. A limit of a function {eq}\displaystyle \lim_{x \to a} f(x) {/eq} is nothing but the limiting value the function approaches as we approach the value {eq...
f / g if g(a) 0 If f and g are continuous at a and c is a constant, then the following functions are also continuous at a: 8 Theorem (a) Any polynomial is continuous everywhere; that is, it is continuous on = (-∞, ∞). (b) Any rational function is continuous whenever it ...
The limit of a constant (lim(4)) is just the constant, and the identity law tells you that the limit of lim(x) as x approaches a is just “a”, so: The solution is 4 * 3 * 3 = 36. Note: We don’t need to know all parts of our equation explicitly in order to use the ...
Discuss the continuity of the function. f(x) = (x^2-4/x+2). f is discontinuous at what value of x? Use the graph to determine the limit, and discuss the continuity of the function. (a) \lim\limits_{x\ \to\ c...

We then need to find a function that is equal to h(x)=f(x)/g(x)h(x)=f(x)/g(x) for all x≠ax≠a over some interval containing aa. To do this, we may need to try one or more of the following steps: If f(x)f(x) and g(x)g(x) are polynomials, we should factor ...
The limit shows that as we get closer and closer to {eq}a {/eq}, the expression of function approaches a specific value. Answer and Explanation: Given: {eq}\lim_{x\rightarrow a} f(x)= 0 \ \lim_{x\righ...
It follows that tapering increases the asymptotic variance of the estimates by a constant factor. All results are proved under integrability conditions on the spectra. A functional limit theorem for the empirical spectral function is also given without assuming all moments of the underlying process to...
Examples of linear functions: f(x) = x, f(x) = 2x – 2, f(x) = x + 1. Domain and Range of a Linear Function The domain and range of a linear function is usually the set of real numbers. There is an exception: if the function is constant (e.g. f(x) = 2) then the ra...
