Answer:

Step-by-step explanation:
Given functions are:

We have to find:
(s.t)(x) => this means we have to multiply the two functions to get the result.
So,

Also we have to find
(s-t)(x) => we have to subtract function t from function s

Also we have to find,
(s+t)(-3) => first we have to find sum of both functions and then put -3 in place of x

Putting x = -3

Hence,

Answer:2.98
