1. mohon bantuannya The picture is a graph of quadratic function......
Persamaan umum fungsi kuadrat :
f(x) = Ax² + Bx + C
Diketahui grafik fungsi f(x) melewati titik :
» (3 , 0)
=> f(3) = 0
=> A.(3)² + B.(3) + C = 0
=> 9A + 3B + C = 0 ( i )
» (–1 , 0)
=> f(–1) = 0
=> A.(–1)² + B.(–1) + C = 0
=> A - B + C = 0 ( ii )
» (0 , 3)
=> f(0) = 3
=> A.(0)² + B.(0) + C = 3
=> C = 3
Subtitusikan nilai C ke ( i ) :
9A + 3B + C = 0
9A + 3B + 3 = 0
9A + 3B = –3 ( iii )
Subtitusikan nilai C ke ( ii ) :
A - B + C = 0
A - B + 3 = 0
A - B = –3 ( iv )
Eliminasi ( iii ) dan ( iv ) :
( iii ) : 9A + 3B = –3
(iv) × 3 : 3A - 3B = –9
________________ +
12A = –12 => A = –1
Subtitusikan nilai A ke ( iv ) :
A - B = –3
–1 - B = –3 => B = 2
Substitusikan nilai A, B, dan C ke persamaan fungsi kuadrat :
f(x) = Ax² + Bx + C
f(x) = (–1)x² + (2)x + (3)
Jadi, persamaan fungsi kuadrat grafik tersebut adalah : f(x)=–x²+2x+3

13. Diagram 5 shows the graph of a quadratic function y = f(x)
a. y = 21+4x-x²
0 = 21+4x-x²
0 = (7-x)(3+x)
x = 7 atau x = -3
b. mencari sumbu simetri di turunan pertama:
y = 21+4x-x²
y' = 4 - 2x ; subtitusi y' = 0 (karena pada titik puncak, m=0)
0 = 4 - 2x
2x = 4
x = 2 ← sumbu simetri

16. kak..pliss jawab dong...important!plisss find the trigonometric function of the graph. jawab yaa :
Jawab:
4 tan x°
Penjelasan dengan langkah-langkah:
perhatikan bahwa di kuadran I (sudut 0° sampai 90°) nilai sudutnya positif, maka fungsi trigonometri yang digunakan adalah sinus atau tangen
lalu pada sudut 90° sampai 180° (kuadran II) nilai nya negatif, maka fungsi trigonometri diatas cosinus atau tangen
dari kedua kesimpulan diatas, maka jelas fungsi yang dipakai adalah tangen. perhatikan bahwa
tan 45° = 1
maka
4 tan 45° = 4
maka kemugkinan fungsi diatas berbentuk
4 tan x°
cek
4 tan 135° = 4 tan (180° - 45°) = 4 (-tan 45°) = 4.(-1) = 4×(-1) = -4 (sesuai)
4 tan 225° = 4 tan (180 + 45°) = 4 tan 45° = 4×1 = 4 (sesuai)
Jadi fungsi trigonometri yang dipakai adalah 4 tan x°
