Hi. I’m getting the students to enter an equation and graph it, but I’d like for the domain to be automatically restricted to 0 <= x <=11 once they submit their answer. Any way I can do it? Also, the equation is of the form y=7.5x+10. But I’d really like them to be able to input C=7.5d+10 Is that …
