The question is asking for the graph that does not represent the graph of a function. Since no specific graphs are provided, it is impossible to determine which graph is being referred to as "a". Therefore, an explanation cannot be generated.

The given question asks us to write a number in completed square form and find its minimum value. The numbers given are 11, 7, 0, and -1. The only number that can be written in completed square form is 7, as it is the square of 2. Therefore, the minimum value is 7.

The equation has two roots because it is a quadratic equation. A quadratic equation can have a maximum of two distinct solutions.

The equation of a line that is parallel to line l will have the same slope, which is 6. Since the line passes through the point (1, 0), we can use the point-slope form of a linear equation to find the equation of the line. Using the point-slope form, we have y - 0 = 6(x - 1), which simplifies to y = 6x - 6. Therefore, the equation of the line through (1, 0) parallel to l is y = 6x - 6.

The equation y = 2x - 1 represents a straight line with a slope of 2 and a y-intercept of -1. This means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 2. The line intersects the y-axis at -1, indicating that when x is 0, y is -1. Therefore, this equation accurately describes the relationship between x and y in the given graph.
