Answer

The value of the function $f (x) = 3 x^{2} + 4$ at $x = 2$ is $16$

Steps

Step 1 ：To find the value of the function at a specific point, we need to substitute the given value into the function. In this case, we need to substitute $x = 2$ into the function $f (x) = 3 x^{2} + 4$ .

Step 2 ：Substitute $x = 2$ into the function: $f (2) = 3 (2)^{2} + 4$

Step 3 ：Simplify the expression to get the final answer: $f (2) = 16$

Step 4 ：The value of the function $f (x) = 3 x^{2} + 4$ at $x = 2$ is $16$
