See the entire solution process below:

Explanation:

To evaluate #w(-4)# we need to substitute #color(red)(-4)# for every occurrence of #color(red)(t)# in the function from the problem:

#w(color(red)(t)) = color(red)(t) - 5# becomes:

#w(color(red)(-4)) = color(red)(-4) - 5#

#w(color(red)(-4)) = -9#
