Final score
How many goals you scored out of 10.
The ball starts at one point and the goal is at another: of several possible functions, which trajectory scores? You read each expression (a line, a parabola, a piecewise function) and check whether it passes where it needs to.
There are ten questions going from easy to hard, with no timer. It trains exactly what is hardest about functions: linking the formula to the shape of the graph without having to draw it all.
