Tolong dibantu nomor 1 tentang fungsi.poinnya lumayan

Answer 1

Answer 2

F(x)=x+2
g(x)=2x-1
pertanyaan
a.(f+g)x
b.(f-g)x
c.(f×g)x
d.(f/g)x
misal bilangan real {2}
f(2)=x+2=2+2=4
g(2)=2(2)-1=4-1=3

a.4+3=7
b.4-3=1
c.4×3=12
d.4/3=1,33
atau caranya
a.f(x)+g(x)
=x+2+2x-1
=3x-1
b.f(x) - g(x)
=x+2-2x-1
=-x-1
c.f(x) × g (x)
=(x+2) × (2x-1)
=2x^2-x+4x-2
=2x^2+3x-2
