pliss tolong bgt bantuu no.35 bsk us mtk soalnyaa:(

•) f(x) = ax + d
f(-3) = -3a + d
-3a + d = -15
•) f(x) = ax + d
f(3) = 3a + d
3a + d = 9

-3a + d = -15
3a + d = 9
_________(-)
-6a = -24
a = 4

3a + d = 9
3(4) + d = 9
d = 9 - 12
d = -3

Nilai dari f(2) adalah
f(2) = 2a + d
f(2) = 2(4) - 3
f(2) = 8 - 3
f(2) = 5
