Question

Evaluate 3x for x = −2, x = 1, and x = 3. Question 18 options: A) 1∕3, 0, 9 B) 1∕9, 3, 27 C) 9, 3, 27 D) 1∕9, 9, 27

Answer 1

Answer: B) 1/9, 3, 27

Step-by-step 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

$3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\ \ \ [\because\ a^{-n}=\dfrac{1}{a^n}]$

At x= 1, we have

$3^1=3$

At x= 3

$3^3=3\times3\times3=27$

So, the values of  $3^x$ for  

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