Question 1

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?

Accepted Answer

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

Answer

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.

Answer

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

Answer

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

Question 2

The graph of $$f\left(x\right)=x^2$$ was transformed to create the graph of $$g\left(x\right)=f\left(x\right)-9$$ . Which statement about the graphs is true?

Accepted Answer

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

Answer

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

Answer

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

Answer

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