1. Answer: Vertical shift up 3 units and vertical stretch by factor of 2

Explanation:

f(x) = √x

g(x) = 2√x + 3

  • adding 3 is a vertical shift up 3 units
  • multiplying by 2 is a vertical stretch by factor of 2

2. Answer: Domain: [0, ∞)

Range: [3, ∞)

Explanation:

g(x) = 2√x + 3

Domain: The restriction on "x" is that the radical must be greater than or equal to 0. So, x ≥ 0 Interval Notation: [0, ∞)

Range: Since the radical must be greater than or equal to 0, then 2√x is also greater than or equal to 0. Add 3 to that and y ≥ 3. Interval Notation: [3, ∞)
