suatu fungsi dirumuskan f(x) = px+q. jika f(-2) = 14 dan f(-3) = -1, maka nilai f(5) adalah

f(-2) = -2p + q = 14
f(-3) = -3p + q = -1
---------------------------- -
p = 15

-2p + q = 14
-2(15) + q = 14
-30 + q = 14
q = 14 + 30
q = 44

f(5) = 5p + q
f(5) = 5(15) + 44
f(5) = 119

semoga membantu （＾ｖ＾）
