Responses

increasing because a>1

increasing because A is greater than 1

decreasing because 0<a<1

decreasing because 0<a<1


increasing because b>1

increasing because b is greater than 1

decreasing because 0<b<1

decreasing because 0<b<1

Answer 1

Decreasing, because the base 1/2 satisfies 0 < b < 1. (The factor 4 is just a vertical stretch and doesn't affect increase/decrease.)
