Penjelasan dengan langkah-langkah:

DIKETAHUI:

f (3) = -5

f (-2) = 5

f (x) = a×+b

Ditanya: Berapa rumus fungsi??

==============================================

3a + b = – 5

– 2a + b = 5

______________-

5a = – 10

a = – 10 : 5

a = – 2

3a + b= – 5

3 x ( – 2 ) + b = – 5

– 6 + b = – 5

b = – 5 + 6

b = 1

_________________________

ax + b

– 2x + 1
