Butuh bantuan banget please!!!
Jawaban No. 1
f(x) = 3x² - 5x + 2
g(x) = 2x + 1
f ( - 2 )
= 3 ( - 2 )² - 5 ( - 2 ) + 2
= 3 ( 4 ) + 10 + 2
= 12 + 10 + 2
= 24
( g o f ) ( x )
= g [ f(x) ]
= 2 ( 3x² - 5x + 2 ) + 1
= 6x² - 10x + 4 + 1
= 6x² - 10x + 5
Jawaban No. 2
1/12 Putaran
= 1/12 × 360°
= 30°
1/12 Putaran
= 30° / 180° π rad
= 1/6 π rad
3/4 Putaran
= 3/4 × 360°
= 3 × 90°
= 270°
3/4 Putaran
= 270° / 180° π rad
= 3/2 π rad
