Question

Dadas as Funçoes F(x)=2x-4,g(x)=-3x+1 e h(x)=X²-3 calcule:
a)f(g(2))
b)g(f(-1))
c)h(f(3))
d)f(f(x))
e)g(h(x))
f)h(f(x))
f)f(g(h(x)))

Answer 1

a) f(g(2))=2.(3.2 + 1)-4=10
b) g(f(-1))=3.(2.-1 - 4) +1=-17
c)h(f(3))=(2.3-4)²-3= 1
d)f(fx))=2.(2x-4) - 4=4x-12
e)g(h(x))=3.(x²-3)+1=3x²-8
f)h(f(x))=(2x-4)²-3=4x²-16x+13
f)f(g(h(x)))=2.(3x²-8)-4=6x²-20
