Answer:
1. Growth
2. Decay
3. Decay
Step-by-step explanation:
Growth means as x increases, y increases too. On the other hand, decay means as x increases, y decreases. There's the theory for exponential function regarding this growth and decay.
Growth
If the base is not a decimal or a fraction then it's growth.
Decay
If the base is a decimal or a fraction then it's decay.
From the problem, first function has base of 5. Hence, it's growth. On the other hand, second and third function both have decimal and fraction as the base. Hence, it's decay.
When considering growth or decay graph, we can ignore the coefficient since it doesn't determine the growth and decay. The only thing that determines if a function increases or decreases is the base under the exponent.
