Evaluate the piecewise-defined function for the given values of x by matching the domain values with the range values

For x = -4
 f (x) = x + 2
 We evaluate the value of x = -4
 f (-4) = (- 4) +2
 f (-4) = - 2

 For x = 4
 f (x) = - 2x + 4
 We evaluate the value of x = 4
 f (4) = - 2 (4) +4
 f (4) = - 8 + 4
 f (4) = - 4

 For x = 0
 f (x) = 3x-4
 We evaluate the value of x = 0
 f (0) = 3 (0) -4
 f (0) = 0-4
 f (0) = - 4

 
 f (-4) = - 2
 f (4) = - 4
 f (0) = - 4

The answer is idk yo
