    The function f(x) = x was transformed to form g(x) = f(x) + 27. Which statement is true about the graphs of f and g?

•    The graphs of f and g are not parallel, and the graph of f is translated 27 units up to create the graph of g.

• The graphs of f and g are not parallel, and the graph of f is translated 27 units down to create the graph of g

• The graphs of f and g are parallel, and the graph of f is translated 27 units up to create the graph of g

• The graphs of f and g are parallel, and the graph of f is translated 27 units down to create the graph of g

• The graph of g is a reflection of the graph of f across the x-axis.

• The vertex of the graph of g is 9 units to the right of the vertex of the graph of f.

• The graph of g is a reflection of the graph of f across the y-axis.

• The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.

1)      For quadratic function f, the solutions to the equation f(x) = 0 are the solutions  x = -8 and x = -4  ? Which function could f represent?

• x^2-12x+32

• x^2+12x+32

• x^2+12x-32
