Question

Jawab donk yg (x+3)(2x-1) diubah menjadi kayak no 15 yg 5x-1

Answer 1

F(x) = (x+3)(2x-1)
f(x) = 2x² + 5x - 3
domainnya (-3,-2-,1,0,1,2,3)
f(-3) =(-3+3) { 2(-3) -1} --> f(-3)= 0
f(-2) = (1)(-5)= -5
f(-1) = 2(-2-1) = -5
f(0) = (0+3)(0+1) = 3
f(1) = 4(1) = 4
f(2) = 5 (3)= 15
f(3)= 6(5)= 30
= (-5, 0, 3, 4, 15, 30 }

Answer 2

Maaf kalo salah
(x+3)(2x-1)
<=>2x-1x+6x-3
<=>1x+6x-3
<=>7x-3
