Just wondering if its ok to get the coordinates of a graph using the calculator. I've been told you have to do the calculations yourself, but according to marking scheme ...
Middle lines of table do not have to be shown
Candidates may choose not to use a table
Points might not be listed, mark on position on graph
* Graph constitutes work in this question
if you mean just getting the coordinates by using the domain and the formula , then you can use the calculator! Just write out the formula , substitue in the numbers and use the calculator to get your coordinates! :)
