Question

what are the domain and range of (f(x) = 2(3^x))?

domain: ((-infty, infty)); range: ((0, infty))
domain: ((-infty, infty)); range: ((2, infty))
domain: ((0, infty)); range: ((-infty, infty))
domain: ((2, infty)); range: ((-infty, infty))

Answer:

• domain: \((-\infty,\infty)\); range: \((0,\infty)\) (Correct answer)
• domain: \((-\infty,\infty)\); range: \((2,\infty)\)
• domain: \((0,\infty)\); range: \((-\infty,\infty)\)
• domain: \((2,\infty)\); range: \((-\infty,\infty)\)
