(a) Find the \( x \) -intercepts of the function \( y = x ^ { 2 } - 5 x - 14 . \) 

(You may use either factoring or the quadratic formula.) (b) By putting \( x = 0 \) , find the \( y \) -intercept. (c) Solve \( \frac { d y } { d x } = 0 \) and hence find the coordinates of the stationary point. (d) By examining the sign of \( \frac { d ^ { 2 } y } { d x ^ { 2 } } \) , establish the nature of the stationary point. (e) Sketch a graph of the function, indicating all important features.
