How Do You Make a Table of Values in Google Sheets?

Suppose you want to generate a table of values from a formula…perhaps to help evaluate a limit. Google Sheets (or any spreadsheet) can quickly generate the values.

Make a table of values for f (x) = 7x2 + 1 for x = 0, 0.9, 0.99, 0.999, 0.9999.

1.  Open Google Sheets.

2.  In the first row place the name of the input variable and the function’s name. We will put the values of the independent variable the first column (A) and the values of the dependent variable in the second column (B).

3.  In cells A2 through A6, put the values of the independent variable for the table.

4.  Click the mouse in cell B2. Enter the formula in that cell by typing =7*A2^2+1.

5.  Press Enter to evaluate the formula in cell B2.

6.  Click the mouse in cell B2. You will see a black outline around the cell. Use the mouse to grab the fill handle in the lower right hand corner of the black outline.

7.  Click on this handle. While holding the left mouse button down, drag the mouse to cell B6.

8.  When the mouse button is released, cells B2 through B6 are filled with the function values corresponding to the inputs in column A.

How Do You Compute a Limit Using a Table?

In each of the next two examples, the value of the limit is the same as the value of the function at the point it approaches. This is typically the case for any polynomial.

For functions that are not polynomials, a table i often in order to evaluate the limit. In each of the following two examples, the output of the function grow more positive or more negative. This means the different limits do not exist.

However, a very similar looking fraction may also lead to a limit that does exist. In the next two examples, the limits do exist even though the functions are undefined at the point the x value is approaching.
