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.
Answer: 20.57142857
Step-by-step explanation:
148 = 3x + 3 + 4x + 1
