Question

Are the following functions exponential growth or decay?
Graphing Exponentials

a) f(x)=10(2)x

is this exponential growth? or exponential decay?

b) f(x)=2(0.5)x

is this a exponential growth? or exponential decay?

Answer 1

Answer:

a) growth b) decay

Step-by-step explanation:

In the function f (x) = b^x when b > 1, the function represents exponential growth.

In the function f (x) = b^x when 0 < b < 1, the function represents exponential decay.

a)b=2 > 1 this function growth

b)b=0.5 < 1 this function decay
