Answer: $1248$

Explanation:1. Set up the equation: We are given the function $g(x) = \dfrac{x}{2}$. We are also given that $g(x) = 624$. So, we can set the expression for $g(x)$ equal to $624$: $\dfrac{x}{2} = 624$

2. Solve for x: To isolate x, multiply both sides of the equation by 2: $2 \times \dfrac{x}{2} = 2 \times 624$ $x = 1248$

3. Verify the solution (optional): Substitute $x=1248$ back into the function $g(x)$: $g(1248) = \dfrac{1248}{2} = 624$. This matches the given condition, so the value of x is correct.

4. Conclusion: The value of x for which $g(x)=624$ is $1248$.
