Use the four-step process to find \( f^{\prime}(x) \), and then find \( f^{\prime}(1), f^{\prime}(2) \), and \( f^{\prime}(3) \). \[ f(x)=2+7 \sqrt{x} \] \[ f^{\prime}(x)=\frac{7}{2 \sqrt{x}} \] \[ f^{\prime}(1)= \] (Simplify your answer. Type an exact answer, using radicals as needed. Use the expression.)
