About Quadratic function.. Kindly answer the Follow-up Questions

Activity 2: What's My Value? Complete table of values then sketch the graphs of the quadratic functions in one (1) plane and answer the follow up questions. ( You may use different colored pens to sketch each graph).

What can you say about the graphs of (y = 5x2 and y = -5x2), (y = x2+2x+1 and y = -x2-2x-1), and (y = -3x2 +1 and y = 3x2 +1)? 2. How do you compare and contrast each graph
