For the piecewise function, find the values \( g(-7), g(4) \), and \( g(7) \). \[ g(x)=\left\{\begin{array}{l} x+9, \text { for } x \leq 4 \\ 6-x, \text { for } x>4 \end{array}\right. \] \[ g(-7)= \]

Step 1 ：g(-7)=(-7)+9

Step 2 ：g(-7)=2

Step 3 ：g(4)=(4)+9

Step 4 ：g(4)=13

Step 5 ：g(7)=6-(7)

Step 6 ：g(7)=-1
