See the entire evaluation process below:

Explanation:

To evaluate this function you need to substitute #color(red)(-6)# for every occurrence of #color(red)(x)# in the function and then calculate the result:

#p(color(red)(x)) = -color(red)(x) - 2# becomes:

#p(color(red)(-6)) = -color(red)((-6)) - 2#

#p(color(red)(-6)) = color(red)((6)) - 2#

#p(color(red)(-6)) = 4#
