Three of your breadcrumbs from the previous activity have been drawn on the screen as red dots. These represent the slope of line [code]g[/code] when x is -1, when x is 0 and when x is 1. The change in y is constant from one to the next, so the relationship between these points is linear.[br][br]Can you come up with a linear function that describes all three at once? Type it into the input bar as [code]f'(x)=CODE[/code]. Obviously, replace "CODE" with the algebraic code for a linear function (hint: [code]mx+b[/code]).
