Select the correct texts in the table. Consider function \(f\) 

\(f ( x ) = \left\{ \begin{array} { l l } { - \frac { 1 } { 4 } x ^ { 2 } + 6 x + 36 , } & { x < - 2 } \\ { 4 x - 15 , } & { - 2 \leq x < 4 } \\ { 3 z - 4 , } & { x > 4 } \end{array} \right.\) 

Are the statements about the graph of function ftrue or false? 

The graph crosses the \( y \) -axis at \( ( 0 , - 15 )\) 

The graph has a point of discontinuity at \( x = - 2 \) .

 The graph is increasing over the interval \( ( 4 , \infty ) \) .

 The graph is decreasing over the interval \( ( - 12 , - 2 ) \) 

The domain of the function is all real numbers.
