Y-intercept: Let x = 0. Result: 5x=0, and x= 0. y-intercept is (0,0).
Similarly, x-int. is (0,0) (after going thru the same procedure: set y=0 and find x)
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,
