ANSWER
1/3; 3; 27
EXPLANATION
We want to complete the missing table by using the function:
[tex]y=3^x[/tex]To do this, we will substitute the values in the table for x and simplify to find y:
[tex]\begin{gathered} \text{when x = -1} \\ y=3^{-1} \\ y\text{ = }\frac{1}{3} \\ \text{when x = 1} \\ y=3^1 \\ y\text{ = 3} \\ \text{when x = 3} \\ y=3^3 \\ y\text{ = 27} \end{gathered}[/tex]Those are the missing values in the table.
