Answer: B) 1/9, 3, 27

Explanation:

Here, we need to evaluate
3^x for
x = -2, x = 1, \text{ and } x = 3.

So, we substitute values of x in the given function.

At x= -2, we have


3^(-2)=(1)/(3^2)=(1)/(9)\ \ \ [\because\ a^(-n)=(1)/(a^n)]

At x= 1, we have


3^1=3

At x= 3


3^3=3*3*3=27

So, the values of
3^x for

Thus, the correct answer is B) 1/9, 3, 27
