The Deep Dive
To analyze the graph of \( y=\sqrt{-4x-36} \), let's break it down. The expression under the square root can be rewritten as \( \sqrt{-4(x+9)} \). This shows us that the graph reflects over the \( x \)-axis due to the negative coefficient and translates 9 units left because of \( (x+9) \). Finally, the factor of 4 indicates a vertical stretch by a factor of 2 (since the square root of 4 is 2). So the graph is stretched by a factor of 2, reflected over the \( x \)-axis, and translated 9 units left. The correct answer is: stretched by a factor of 2, reflected over the \( x \)-axis, and translated 9 units left.
