The expressions below represent either exponential growth or exponential decay. Check all the expressions that represent exponential decay.

5^x

3 (0.75) ^2t

35 (2.4) ^x

5000 (1.04) ^3t

0.05^x

500 (0.005) ^t

Answers B, E and F (1, 5 and 6).

Step-by-step explanation:

In an exponential equation, (y=ab^x), the "b" value must be a decimal less than 1 (but greater than 0) for it to be considered an exponential decay function. Only equations B, E and F have a "b" value that fits this criteria.
