Right now my equations reads: f(x) = 3.11x + 0.038, however I need to change f(x) and x to different variables. This is in the Calc Spreadsheet.

I believe the asker wants to do something like change the equation to “g(t) = 3.11t + 0.038” instead.

See: Trend Lines

Default equation uses

`x`

for abscissa variable, and`f(x)`

for ordinate variable. To change these names, select the trend line, chooseFormat - Format Selection – Typeand enter names in`X Variable Name`

and`Y Variable Name`

edit boxes.

In a spreadsheet F(x) and x refer to cells. Thus, if you change the cells the values will change.

e.g.

A1, 2, 3, 4, 5,… contains the x values

B1, 2, 3, 4, 5,… contains the F(x) values, which means for the first row B1 contains “=3.11*A1+0.038”

Now you can replace the A1, 2, 3, 4, … with other cells and can place the related formula into other cells as well.
