The correct answer is C. \(g(x) = 3(x+2)^{2}+5\).

## Step 1<br />The problem involves the transformation of the function \(f(x) = x^{2}\). The transformations are:<br />- Moving the graph left 2 units<br />- Vertically stretching it by a factor of 3<br />- Shifting the graph up 5 units<br /><br />## Step 2<br />The transformations can be represented as follows:<br />- Moving the graph left 2 units is represented by \(x+2\)<br />- Vertically stretching it by a factor of 3 is represented by multiplying the function by 3<br />- Shifting the graph up 5 units is represented by adding 5 to the function<br /><br />## Step 3<br />Combining these transformations, we get the function \(g(x) = 3(x+2)^{2}+5\).
