Answer:
Explanation:
The graph of quadratic functions are called parabola. If a (literal coefficient of the variable that is squared) is positive, the graph opens upward or right. But since the given functions are squared in the part of x; therefore, the parabola is vertical and its graph opens just upward and downward. If a is negative, the graph opens downward.
