2.14.2 Drawing Graphs - Using a Table

How do we draw a graph using a table of values?

  • Use your calculator
  • THINK what the graph might look like – see the previous notes on being familiar with shapes of graphs
  • Find the TABLE function on your CALCULATOR
  • Enter the FUNCTION – f(x)
    (use ALPHA button and x or X, depending on make/model)
    (Press = when finished)
    (If you are asked for another function, g(x), just press enter again)
  • Enter Start, End and Step (gap between x values)
  • Press = and scroll up and down to see y values
  • PLOT POINTS and join with a SMOOTH CURVE

 

  • If your calculator does not have a TABLE function then you will have to work out each y value separately using the normal mode on your calculator
  • To avoid errors always put negative numbers in brackets and use the (-) key rather than the subtraction key
