Example Problem 1: Determining if a Function is Continuous at a Point Within An Interval Determine if the function {eq}f(x)=\dfrac{x^2-1}{x-1} {/eq}is continuous over the interval (-5, -2). Use this to determine if the function is continuous at x = -3. ...
For the function f(x)=−2cos(1x), determine if limx→0f(x) exists. Step 1: Examine the graph of f(x) near x=a. Check both limx→a−f(x), the limit from the left, and limx→a+f(x), the limit from the right. Does ...
A linear function creates a straight line when graphed on a coordinate plane. It is made up of terms separated by a plus or minus sign. To determine if an equation is a linear function without graphing, you will need to check to see if your function has the characteristics of a linear ...
This example of the IF function is a bit more involved. The idea here is to see if an item we owe money on is past due, and if it is, we're seeing whether or not that amount is in our budget so that we can pay it off. If both of those statements are true, we can see in...
IFS is an upgraded version of theIF function in Excel. The syntax and the usage are similar, except that IFS is designed to take in multiple conditions. The IF function required nesting multiple IF functions to define multiple conditions, while the IFS can define it all with a single functio...
I want to use the IF function to determine if the "delivery date" on cell "B" surpassed the "ship date" on cell "A" by say 1 day, then it's Good,...
function to determine if there is an error in E2, and if there is, the CONCATENATE function combines the values in D2, E2 and F2 (the function replaces the error with a 0), and displays the resulting text string. Note the formula also uses spaces (““) to...
A nested statement is one where one function is used as the argument of another function. Expanding on our previous example, we could have two cells being evaluated in order to determine the outcome of cell D19: If cell C19 is equal to the word “Yes” then cell D19 should calculate ...
function checkOverlapping() { var theDoc = app.activeDocument; var selectedLayers = getSelectedLayersIdx(); if (selectedLayers.length != 2) {alert ("Please select the two layers you would like to check"); return null;} selectLayerTransparency(selectedLayers[0], false); sele...
Our goal is to determine the maximum sales for each category: Clothing, Shoes, and Eyewear, using the Excel MAXIFS function. Excel Using MAXIFS function Step 1:The first step is to call the MAXIFS function, click on an empty cell and enter the MAXIFS function: “=MAXIFS(“. Remember to ...
