Question

(Q5) Decide if the function is an exponential function. If it is, state the initial value and the base. y=3.1^x

Answer 1

D

Explanation:

Exponential equation takes the form
`y=ab^x` where

a is the initial value ( a ≠ 0), and

b is the base ( b ≠ 1)

The equation given can be written as
`y=3.1^x\\y=1*3.1^x`. Thus, it is an exponential equation.

So a = 1 and b = 3.1

Thus we can say that the initial value = 1 and the base is 3.3
