Suatu fungsi dirumuskan g(x) = ax+b. jika g(3) = -5 dan f(-2) = 10,maka nilai g(5)+g(2)=

G(3) = 3a + b = -5
g(-2) = -2a + b = 10
__________ _
5a = -15
a = -3
3a + b = -5
3.(-3) + b = -5
-9 + b = -5
b = -5 +9
b = 4

g(5) = ax + b. g(2) = ax + b
= -3.5 + 4. = -3.2. + 4
= -15 + 4. = -6 +4
= -11. = -2

g(5) + g(2)
= -11 -2
= -13

semoga tidak salah
mohon diteliti lagi,, karena saya terkadang kurang teliti. . thx
