A graph of a quadratic function is shown. What are the x-intercepts of the function?

Shade the TWO correct circles that represent the points.

The function f(x) = x was transformed to form g(x) = f(x) − 23.

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 23 units up to create the graph of g.

• The graphs of f and g are not parallel, and the graph of f is translated 23 units down to create the graph of g.

• The graphs of f and g are parallel, and the graph of f is translated 23 units up to create the graph of g.

• The graphs of f and g are parallel, and the graph of f is translated 23 units down to create the graph of g.
