Hello!
We have the equation below:
[tex]\boxed{y=a\left(b\right)^x}[/tex]Also, we know the values of the variables:
a = 128;
b = 3;
x = 2;
So, let's replace the values and solve it:
[tex]\begin{gathered} y=a\left(b\right)^x \\ y=128\times(3)^2 \end{gathered}[/tex]First, we'll solve the power:
[tex]\begin{gathered} y=128\times9 \\ y=1152 \end{gathered}[/tex]Alternative A.
