Question

Suatu fungsi f dirumuskan dengan f(x) = 2x + 3 tentukan nilai dari f(3), f(-2), dan f(1 per 2)

jawab:
1. f(x) = 2x- 3
f(3) = 2(..)-3
=...
=...

TOLONG BANTU YAHH ;(

Answer 1

F (x) = 2x - 3
f (3) = 2(3) - 3
f (3) = 6 - 3 = 3

f (-2) = 2(-2) - 3
f (-2) = -4 - 3 = -7

f (1/2) = 2 (1/2) - 3
f ( 1/2 ) = -2
