Performance notes
A graphing calculator plots equations on its LCD, so screen size and resolution govern how clearly a curve is read. The listing gives the screen size but not the pixel grid or memory, so how many graphs fit at once is unknown. Entry speed depends on key layout and menu depth, which the listing does not describe.
