Question

The graph of the quadratic parent function was transformed to create the graph g(x) = f(x) - 9. Which statement about the graphs is true?

Answers Choices
A The graph of g is a reflection of the graph of f across the x-axis.
B. The vertex of the graph is 9 units to the right of the vertex of the graph of f
C. The graph of g is a reflection of the graph of f across the y-axis.
D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.

Answer:

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

Explanation:

Subtracting 9 from the function value moves every point on the graph down 9 units. That includes the y-intercept.

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