Question

Given the following functions, evaluate each of the following

Answer 1

Answer:

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

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

Step-by-step explanation:

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

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

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

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

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

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