Answer

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

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 $f(x)=3x^2+4$.

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 $f(x)=3x^2+4$ at $x=2$ is $\boxed{16}$
