4. which distance-time graph respresents a body whose speed is decreasing
Which distance-time graph respresents a body whose speed is decreasing is the line on the graph is sloping downwards. Additionally, you may also notice that the distance between points on the graph is getting smaller as well - this, too, is an indication that the speed is slowing down.
PembahasanPada pokok bahasan kinematika, grafik dijadikan salah satu representasi untuk menjelaskan konsep gerak. Konsep-konsep kinematika gerak meliputi perpindahan, kecepatan dan percepatan yang berhubungan dengan fungsi waktu. Bentuk-bentuk gerakan partikel (benda) dapat diketahui dengan menelaah grafik kinematika.
Pada umumnya grafik jarak-waktu ditunjukkan dengan grafik garis yang dapat menjelaskan suatu benda pergerakannya cepat atau lambat dalam waktu tertentu. Ada faktor lain yang dapat mempengaruhi grafik jarak-waktu (seperti percepatan), jadi penting untuk mempertimbangkan semua ini sebelum membuat kesimpulan. Namun, jika Anda melihat kemiringan ke bawah atau jarak antar titik yang lebih kecil, dapat dikatakan bahwa kecepatan yang ditunjukkan oleh grafik memang menurun.

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
14. 5. The points (4, a), (5,-2) are some points on the graph of y = 2x + 7. Find without plotting the graph, (a) the value of a, (b) the value of b.
Penjelasan dengan langkah-langkah:
(4, a) ------> y = 2x + 7
a = 2 . 4 + 7
= 8 + 7
= 15
so, value of a is 15
15. Line l intersects the graph of the function f(x) = 2x² - 4x + 1 at two points where x= -1 and x=2, respectively. What is the slope of line l? a. -2b. -2/3c. 3/2d. 2
when x = -1
y = 2x² - 4x + 1
y = 2(1) - 4(-1) + 1
y = 7
when x = 2
y = 2x² - 4x + 1
y = 2(4) -4(2) +1
y = 1
m (x2-x1) = y2-y1
m (2+1) = 1-7
m = -6/3
m = -2_________
