Question

As funções f e g são dadas por f(x)=3x+2m e g(x)=-2x+1. Calcule o valor de m sabendo que f(0)+g(1)=3

Answer 1

$f(x) = 3x+2m \\\\ f(0) = 3(0)+2m \\\\ \underline{f(0) = 2m} \\\\\\ g(x) = -2x+1 \\\\ g(1) = -2(1)+1 \\\\ \underline{g(1) = -1} \\\\\\ f(0)+g(1) = 3 \\\\ 2m-1 = 3 \\\\ 2m = 4 \\\\ \boxed{\boxed{m = 2}}$

Answer 2

f(x)=3x+2m e g(x)=-2x+1. Calcule o valor de m sabendo que f(0)+g(1)=3
f(x) = 3x +2m

g(x) = - 2x + 1


f(0) = 3.(0) +2m = 0 + 2m ==> 2m

g(1) = - 2(1) + 1= - 2+1==> - 1

===================================================

f(0) + g(x) = 2m  - 1 = 3

2m = 3+1==> 2m  = 4

m = 2
============================================

f(x) = 3X + 2.m ==>3x +2.2 ==> f(x) = 3x + 4
