Question

Diketahui f(x) = x2+2x+8
g(x) = 2x+1
Ditanya :
a.(f+g) (x) ?
b.(f-g) (x) ?
c.(f.g) (x) ?
d.(f/g) (x) ?
Tolong dijawab yahh,,makasih sebelumnya....:)

Answer 1

F(x)=x2+2x+8
fx=4x+8
f=4x+8/x
f=12

gx=2x+1
g=2x+1/x
g=3

a) (f+g) (x)
=(12+3) (x)
=15x

b) (f-g) (x)
=(12-3) (x)
=9x

c) (fxg) (x)
=(12x3) (x)
=36x

d) (f/g) (x)
=(12/3) (x)
=4x
