Use the four-step process to find \( f^{\prime}(x) \) and then find \( f^{\prime}(1), f^{\prime}(3) \), and \( f^{\prime}(4) \). \[ f(x)=2 x^{2}-9 x+10 \] \[ f^{\prime}(x)= \] \( f^{\prime}(1)=\quad \) (Type an integer or a simplified fraction.) \( f^{\prime}(3)=\quad \) (Type an integer or a simplified fraction.) \( f^{\prime}(4)=\quad \) (Type an integer or a simplified fraction.)
