Final answer:
If the a term of a quadratic is positive (+), the U-shape will open upward.
Step-by-step explanation:
If the term of a quadratic is positive, the U-shape of the graph will open upward. When a quadratic equation is in the form of y = ax^2 + bx + c, a positive value of 'a' will make the graph of the quadratic curve upwards.
This means that the vertex of the parabola will be the lowest point, and the arms of the U-shape will open in an upward direction.
