A reader recently asked: I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut the x-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set...
Learn the meaning of the amplitude of a function. Understand the method to find the amplitude of a sine function from the wave formula and graph...
I took a Matlab course over the summer, and now have to graph a problem in calculus. I am rusty on my commands, so I'm not sure which one to use. I am trying to make a 3-d plot of a function f(x,y)=-(x^2-1)^2-(x^2y-x-1)^2. Do I have to open a function, or...
represented by a function, where it crosses the x-axis on the graph. The x-intercept is written as (x, 0), because the y-coordinate is always zero at the x-intercept. If you know the slope and the y-intercept of the function, you can calculate...
Learn how to identify the graph of a function given the graph of it's first derivative & vice-versa, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.
Method 4 – Using FORECAST Function Steps Create a chart and add a trendline (similar to Method 1). In cell F7, enter the following formula: =FORECAST(F6,C5:C12,B5:B12) Press ENTER to obtain the interpolated value. The final graph chart, after adding the interpolate value, will be displ...
As a result, we will get the data points from the graph in a tabular form. Method 2 – Enabling Data Labels This is an easy and quick way to get the data points from a graph. Here, we will not get the data in a tabular form. However, we will see it on the graph in a more...
You’ll find the different graph types under the ExcelInsert tab, in theExcel Ribbon, arranged close to one another like this: Note:The Excel Ribbon is where you can find theHome,Insert, andDrawtabs. Here are some of the differentExcel graph or chart type optionsyou can choose from: ...
You’ll then need to write the formula into cell B2 for your graphing function. Start by writing the “=” symbol in the B2 cell followed by the formula. Don’t leave any spaces after the “=” or else the formula won’t work. For example, if you want to find out what levels ...
Steps to graph a function When graphing functions, we take the following steps: Find the function’s domain and range and keep them in mind as you draw the curve. Find and plot the x-intercept(s) and y-intercept(s). Determine whether or not there are any holes. Find the asymptotes ve...
