Question

Which is an exponential growth function?

f(x) = 6(0.25)x
f(x) = 0.25(5.25)x
f(x) = –4.25x
f(x) = (–1.25)x

Answer 1

this is the answer . f(x) = 0.25(5.25)x

Explanation:

i did the questions and it was right.

Answer 2

For this case, the first thing we must observe is that we have functions of the form:
y = A (b) ^ x
Where
A: initial amount
b: growth rate (b> 1) or decrease (b <1)
x: a variable that is usually time.
We have then:
f (x) = 0.25 (5.25) x
Where,
b> 1
Therefore, the function grows.
Answer:
f (x) = 0.25 (5.25) x
