I was wondering if there is a way to code a formula into the activity builder?
I want to create a functions self checking activity where the students pick any input number and then they will use the given equation to find the output. Desmos will then say that it is correct or not because it can evaluate the answer the student put in.
I know how to create a basic self checking activity by coding what the specific answer has to be however, I was wondering if it was possible to create if there is not one specific answer.
I hope this question makes sense
Students are given the expression 2x+4
The student picks any random x value will then plug their chosen number into the above expression and will get their y
I want to code 2x+4 into the activity that way it does not matter what x the students pick, desmos will be able to check to see if they got the correct answer
