If I ask a student to enter a value for x, then enter the output that value elicits from my function, how would I code a variable for the student's input value.
Input a value for x: ____________
What output value would you get for f(**student number here**) if f(x) = x^2 - 7x + 12?
f(**student number here**) = _______________
Answer code: $x*$x - 7*$x + 12
It's the "$x" that I do not know how to code in Canvas.
