Question

F(x) = 5x+2/3 (Lima (x) pun mencakup pecahan)
g(x) = x^2-4

Maka, f+g(x) adalah ...

Answer 1

F(x) = (5x+2)/ 3
g(x) = x^2 - 4

f +g (x) = f(x)  + g(x) 
(f+g)(x) = (5x+2)/3 + (x^2 - 4)
(f+g)(x) = {(5x+2)+3(x^2- 4)}/(3)
(f+g)(x)= ( 5x+2 + 3x^2 - 12)/(3)
(f+g)(x) = (3x^2 + 5x -10)/(3)
atau = 1/3 ( 3x^2 + 5x -10) = x^2 + ⁵/₃ x - ¹⁰/₃
