Connecting the Dots
Three of your breadcrumbs from the previous activity have been drawn on the screen as red dots. These represent the slope of line
g 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.
Can you come up with a linear function that describes all three at once? Type it into the input bar as f'(x)=CODE. Obviously, replace "CODE" with the algebraic code for a linear function (hint: mx+b).
