Question

Given the following functions, evaluate each of the following

Answer 1

`(f+g)(5) = 40\\(f-g)(5) = 22\\(f*g)(5) = 279`

`(f/g)(5) = 31/9`

Explanation:

`f(5) = (5)^2+2(5)-4\\f(5) = 25+10-4\\f(5) = 31`

`g(5) = 5+4\\g(5) = 9`

`(f+g)(5) = 31+9\\(f+g)(5) = 40`

`(f-g)(5) = 31-9\\(f-g)(5) = 22`

`(f*g)(5) = 31*9\\(f*g)(5) = 279\\`

`(f/g)(5) = 31/9`
