Checkpoint 2

Task - 3 Truths and a Lie

1. Below is the graph of four functions with their equation. Only three of them are correct. Which is the graph where the function and the equation do not match?

$y=\frac{2}{x}+3$                                                         $y=\frac{2}{x}-3$                                                           

$y=\frac{2}{x}+3$                                                          $y=\frac{2}{x+3}$

 2. Task - Students are to draw 4 related graphs with its equation written on the graph. Only three of these graphs should be correct as in the first question.  

For example students could use  $y=x^2+2$ , $y=2x^2$ , $y=(x+2)^2$ , $y=x^2-2$

Or  $y=2^x+3$ , $y=3\times2^x$ , $y=2^x-3$ , $y=-3\times2^x$

3. If possible, share with at least 2 peers (Or with your teacher if sharing with peers isn't possible).

Your peers must find which graph is incorrect.
