The Spreadsheet
By Lauren Lee
Construct a graph of any function y = f(x) by generating a table of values with the x values in one column and the y values in another.
I chose to graph the
function f(x) = x²-1.
I began by selecting values
of x and plugging them into my function.
|
x |
f(x) = x^2 - 1 |
