Explanation of Solution
Given information:
Given function
Calculation:
Consider the equation
It is parabola in the standard from with vertex
Axis of symmetry is
So the graph of the parabola opens downward.
Comparing it with the graph of

Explanation of Solution
Given information:
Given function
Calculation:
Consider the equation
It is a parabola in the standard form with vertex
Axis of symmetry is
Moreover the leading coefficient is positive.
So the graph of the parabola opens upward. Comparing it with the graph of
