      1. The graph will have a vertical stretch by a factor of 7 about the x-axis and a horizontal translation 9 units to the right. This will result in a domain of {x|x ≥ 9, x ∈ R} and a range of {y|y ≥ 0, y ∈ R}.
      3. The graph will have a reflection across the x-axis and a horizontal stretch by a factor of 5 about the y-axis. This will result in a domain of {x|x ≥ 0, x ∈ R}and a range of {y|y ≤ 0, y ∈ R}.
