SOAL MATEMATIKA 1
1.Topik : Eksponen
Bentuk sederhana dari adalah….
Kunci : A
Pembahasan :
2. Topik : Eksponen
Nilai x dari persamaan adalah ….
- 2
- 4
- 6
- 10
- 16
Jawaban : E
Pembahasan :
Bilangan berpangkat di soal adalah bentuk permasalahan bilangan berpangkat pecahan, sehingga cara penyelesaiannya sebagai berikut :
3.Topik : Eksponen
Fungsi eksponensial dari grafik di bawah ini adalah ….
- f(x)=32x
- f(x)=3x
- f(x)=3-x
- f(x)=2x
- f(x)=2-x
Jawaban: B
Pembahasan
Pada grafik di atas dapat dilihat melalui dua titik, yaitu (0,1) dan (1,3). Untuk mendapatkan fungsi eksponensial tersebut, kita harus mensubstitusikan kedua titik yang ada ke dalam persamaan fungsi eksponensial secara umum f(x)=b × ax untuk mencari nilai a dan b, sehingga:
Untuk titik (0,1) didapat f(x)=b × ax
1=b × a0
1=b × 1
b=1
Untuk titik (1,3) didapat f(x)=b × ax=1 × ax=ax (masukkan nilai b = 1)
f(x)=ax
3=a1
3=a
Maka, fungsi eksponensial dari grafik tersebut adalah
f(x) = b × ax
f(x) =1 × 3x
f(x) =3x
4.Topik : Bilangan bentuk akar

Maka urutan dari yang terkecil ke yang terbesar adalah
6.Topik : Logaritma
Hasil dari adalah ….
- 1
- 2
- 3
- 4
- 5
Jawaban: A
Pembahasan:
7.Topik : Logaritma

Jawaban: A
Pembahasan:
8.Topik : Persamaan dan Pertidaksamaan Linier
Nilai x dari persamaan linier 7x+23=4x-1 adalah ….
- -3
- -1
- 0
- 1
- 3
Jawaban: D
Pembahasan
7x+23=4x-1
7x+2=3(4x-1)
7x+2=12x-3
7x-12x=-3-2
-5x=-5
9.Topik : Fungsi Kuadrat
Persamaan kuadrat yang melalui titik-titik (-3, -1), (-1, -5), dan (2, 4) adalah….
- y = x2 + 2x – 4
- y = x2 – 3x – 4
- y = 2x2 + 2x + 5
- y = x2 – 3x + 5
- y = 2x2 + 2x – 5
Jawaban : A
Pembahasan :
Persamaan parabola : y = ax2 + bx + c
Titik (-3, -1) → 9a – 3b + c = -1 ………….(1)
Titik (-1, -5) → a – b + c = -5 …………….(2)
Titik (2, 4) → 4a + 2b + c = 4 …………..(3)
Eliminasi pers. (1) dan (2) :
9a – 3b + c = -1
a – b + c = -5 –
8a – 2b = 4
4a – b = 2 ………………..(4)
eliminasi persamaan (2) dan (3) :
a – b + c = -5
4a + 2b + c = 4 –
-3a – 3b = -9
a + b = 3 ………………..(5)
eliminasikan persamaan (4) dan (5) :
4a – b = 2
a + b = 3 +
5a = 5
a = 1
subsitusikan ke persamaan (5) :
a + b = 3
1 + b = 3
b = 2
subsitusikan ke persamaan (3)
4a + 2b + c = 4
4(1) + 2(2) + c = 4
c = -4
Persamaan kuadratnya : y = x2 + 2x – 4
10.Topik : Sistem Persamaan Linier Kuadrat Dua Variabel (SPLKDV)
Himpunan penyelesaian antara kurva x2+y2-2xy-1=0 dan garis x-2y-2=0 adalah ….
- (0, 1) dan (4,-3)
- (0, 1) dan (-4,-3)
- (0, -1) dan (4,3)
- (0, -1) dan (-4,-3)
- (0, -1) dan (-4,3)
Jawaban: D
Pembahasan:
x – 2y – 2 = 0 → x = 2y + 2
Substitusi x=2y+2 ke persamaan kurva x2+y2-2xy-1=0
(2y+2)2+y2-2(2y+2)(y)-1=0
4y2+8y+4+y2-4y2-4y-1=0
y2+4y+3=0
(y+1)(y+3)=0
y1=-1 dan y2=-3
Substitusikan nilai y yang telah didapatkan ke salah satu persamaan:
Untuk y1=-1, x1=2(-1)+2=0
Untuk y2=-3, x2=2(-3)+2=-4
Maka, penyelesaian sistem persamannya adalah (0, -1) dan (-4,-3).
