• 

• Growth

  Domain: All Real Numbers

  Range: Y > 0

  Y-Int: (0, .5)

  Asymptote: Y = .5

• Growth

  Domain: All Real Numbers

  Range: Y > 0

  Y-Int: (0, .5)

  Asymptote: Y = 0

• Decay

  Domain: X > 0

  Range: All Real Numbers

  Y-Int: (0, .5)

  Asymptote: Y = 0

• Decay

  Domain: All Real Numbers

  Range: Y > 0

  Y-Int: (0, .5)

  Asymptote: Y = .5

Answer explanation

Given the function, the first thing you should do is check b. b = 4 here and 4 > 1 meaning this is a growth function.

Domain is ALWAYS all real numbers.

I am not adding or subtracting anything so my asymptote is Y=0 meaning my Range is Y > 0.

When I plug 0 in for X, I get that Y = 0.5 meaning that my Y-intercept is (0, 0.5).
