The question contains an expression, not an equation. An expression does not have a graph. Furthermore, even if it were an equation, its form suggests that it would be a linear equation and a linear equation does not open in any direction.
It is not possible to answer the question because there is no equation - only an expression.
When 'a' is positive in a quadratic function of the form (y = ax^2 + bx + c), the graph opens upwards. This means the vertex of the parabola is the lowest point on the graph, and as you move away from the vertex in either direction, the values of (y) increase.
An open circle on a line graph indicates that a particular point is not included in the set of data being represented. This typically signifies a value that is either excluded from the domain or is a boundary point that is not part of the solution. For example, in a graph representing a function, an open circle at a point would mean that the function does not take that value at that specific input.
If ( a ) is positive in the quadratic equation ( y = ax^2 + bx + c ), the parabola opens upward. This means that the vertex of the parabola is the lowest point on the graph, and as you move away from the vertex in either direction along the x-axis, the values of ( y ) increase. Conversely, if ( a ) were negative, the parabola would open downward.

Since 'x' and 'y' both appear to the first power, this is a linear equation.That means that the graph is a straight line, and it doesn't 'open'.The line has a slope of -1, and it cuts the y-axis at y=9.

A parabola can open left, down, right, or left on a graph, if that's what you mean:\

Neither statement is true. The graph of the absolute value of a function which is always non-negative will be the same as that of the original function and this need not open in any direction. Also, the graph of y = abs[x*(x-1)*(x+2)] is not symmetrical so there is no coefficient which will determine a line of symmetry.
None of the following sets would.
open dot means < or > but not equal to.
