Question

Considere as funções f(x)=3x+4 e g(x)=2x+5 e h(x)=-5x-3 e calcule:

a)f(x)+g(x)+h(x)
b)f(x)-g(x)-h(x)
c)g(x)-f(x)+h(x)

Answer 1

a) 3x + 4 + 2x + 5 + (-5x - 3)
5x - 5x + 9 - 3 = 6

b) 3x + 4 - (2x + 5) - (-5x - 3)
x - 1 + 5x + 3
6x + 2

c) 3x + 4 - (2x + 5) + (-5x - 3)
3x + 4 - 2x - 5 - 5x - 3
-4x - 4
