What is the domain and range for the function f(x) = 1(2)^x

• Domain: x ∈ ℝ

  Range: y ≥ 1

• Domain: x ∈ ℝ

  Range: y ≥ 0

• Domain: y ≥ 0

  Range: x ∈ ℝ

• Domain: x ∈ ℝ

  Range: y > 0

Answer explanation

Horizontal asymptote! The y value will approach but never equal zero!

• A/F
• B/G
• C/H
• D/J
