. What effect will this have on the graph of the function?

Answer 1

9514 1404 393

Answer:

• reflected across the x-axis
• vertically stretched by a factor of 2
• translated down 7 units

Step-by-step explanation:

When the function y = x³ is transformed to y = -2x -7, there are three transformations involved. The multiplication by 2 causes a vertical stretch by a factor of 2. The leading minus sign causes the function to be reflected over the x-axis, and the addition of -7 causes the graph to be translated down 7 units.
