for the given functions f and g finda fg3 b fxg2 c fg1 STATE
for the given functions f and g find:a) (f+g)(3), b) (fxg)(2), c) (f/g)(1)
STATE THE DOMAIN FOR EACH AS WELL. f(x)= f(x) = 32 and g(x)3x-5
Solution
f(x) = 32 ; g(x) = 3x - 5
a) (f+g)(3) :
(f+g)(x) = 32 +3x - 5 = 3x +27
(f +g)(3) = 3*3 +27 = 9 +27 = 36
b) (fxg)(2)
(f*g)(x) = 32(3x -5)
(f *g)(2) = 32(3*2 - 5) = 32
c) (f/g)(1):
(f/g)(x) = 32/( 3x -5)
(f/g)(1) = 32/(3*1 - 5) = - 16
