Question

Jika f(x) = 2x-1 dan g(x)=4-2x nilai dari f(2) + g(3) adalah

Answer 1

F(x) = 2x - 1
f(2) = 2(2) - 1
      = 4 - 1
      = 3

g(x) = 4 - 2x
g(3) = 4 - 2(3)
       = 4 - 6
       = -2

f(2) + g(3) = 3 + (-2)
                 = 3 - 2
                 = 1

Answer 2

F(x)= 2x-1 g(x)= 4-2x
f(2)= 2(2)-1 g(3)= 4-2(3)
f(2)= 4-1 g(3)= 4-6
f(2)= 3 g(3)= -2

f(2)+g(3)= 3+(-2)
= 1
