I'll do the first one to get you going in the right direction

a)

f%28x%29=e%5E%28-2x%29+%2B+1 Start with the given function


f%28-1%29=e%5E%28-2%28-1%29%29+%2B+1 Plug in x=-1


f%28-1%29=e%5E%282%29+%2B+1 Multiply


f%28-1%29=7.389+%2B+1 Square "e" (which is approximately 2.718...) to get 7.389


f%28-1%29=8.389 Add
