The graph will be that of a parabola

Answer 2

Answer:Here is Ur answer

Step-by-step explanation:

1) when a value of a is greater than 0 ,then the graph representation (curves/parabolas)will be open upward..

2) when a value of a is less than 0 ,then graph representation will have open downwards ..Hope this answer is useful in ur studies..Happy Learning..
