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 also possible?
Many thanks
Ingrid

Current Slide 1:
I added a correct sink for the input (and used that check for your feedback in the note). Also added the “readOnly: true” to the graph, so you’ll get a teacher dashboard checkmark when correct.
Let me know if you’d like any explanations.
Thanks Daniel
This is great. No way would I have thought of this. Awesome.
Thanks
Hi Daniel
I was wondering if you could help me again.
I’d like for students to be able to enter an equation and to restrict the domain themselves. For example, in this activity they can see the line y=5.5x, 0<x<6 already drawn faintly on the graph. I’d like for them to be able to enter the equation in the first box, and then restrict the domain in the second box so that they replicate what is already there.
I’ve tried to use what you did in your last answer, but I keep going in circles.
If you could help, I’d very much appreciate it.

I’m not sure. You might be better off using a full screen graph with some hidden folders, and having students type directly into an expression line.
Thanks for the suggestions! 
I appreciate your time.
Ingrid
I’m not sure if this helps, but the students could do this without a second input using the same notation as you would in the graphing calculator.
Hmm. Not sure why this wasn’t working for me, but was my original strategy to approach.
Thank you for your help gentlemen. Perfect!!
It just didn’t occur to me that I could do it the same way as in the graphing calculator. Duh!
Thanks!
