Help me on 6 and 7 please

Zina [86]

Answer:

6. Growth

7. Decay

Step-by-step explanation:

Rewriting an exponential equation can take many forms. One way to determine if the exponential function is growth or decay is to write the base as (1+a) or (1-a). Since a number greater than 1 is growth and a number less than one decays, this can determine the type of function it is.

$6. f(x) = 3(1.02)^{10t} = 3(1+0.02)^{10t}\\7. y= (0.95)^{t+2} = (1-0.05)^{t+2}$

Since 6 is 1+0.02, it is growth.

Since 7 is 1-0.05, it is decay.
