Generate an interactive graphical quiz on the plotting of quadratic functions
ResourceFunction["QuadraticDescriptionPlotQuiz"][] returns an interactive assessment on plotting quadratic functions. 
Check answer  automatically grades input with feedback 
Next problem  randomly generates a new problem and internally saves the previous problem history 
Print report  prints a description of the problems that have been attempted so far, all guesses made and whether the last guess on each problem was correct 
Generate a quiz on plotting a quadratic function by moving points on a graph:
In[1]:= 

Out[1]= 

Clicking Check answer marks attempts as correct based on whether or not the conditions of the description are met:
In[2]:= 

Out[2]= 

If an attempt does not approximately meet the specified criteria, clicking Check answer marks the attempt as incorrect with a red x:
In[3]:= 

Out[3]= 

For some problems, it may help to turn on "Snap to grid" under the "Display options" menu to more easily get integervalue points:
In[4]:= 

Out[4]= 

Clicking the Print report button returns a description of the problems that have been attempted so far, all guesses made and whether the last guess on each problem was correct:
In[5]:= 

Out[5]=
