NILAI FUNGSI #2

Kita latihan seperti kemarin ya, sampe semua nya bisa baru lanjut

Kerjakan dengan teliti, liat contoh soal jika kurang paham

Multiple Choice

Apakah diagram panah berikut merupakan fungsi ?

FUNGSI

BUKAN FUNGSI

Multiple Select

Dari gambar berikut, manakah yang merupakan fungsi ? (pilih 2)

Sekarang, kita lanjut ke latihan mencari nilai fungsi. Perhatikan contoh dahulu

Nilai fungsi f(x)

Jika diketahui fungsi

$f\ :\ x\ \rightarrow\ 2x-1$

Tentukan nilai dari f(-3) !

Cara :

f\left(x\right)=2x-1

f\left(-3\right)=2\left(-3\right)-1

f\left(-3\right)=-6-1

f\left(-3\right)=-7

Sekarang kita latihan

Next Slide

\rightarrow

Multiple Choice

Diketahui fungsi

f\left(x\right)=3x+4

Tentukan nilai dari f(-2) !

- 2

- 10

Multiple Choice

Diketahui fungsi :

f\left(x\right)=-2x+5

Tentukan nilai dair f(-3) !

- 1

- 11

Multiple Choice

Diketahui fungsi :

g\left(x\right)=1-2x^2

Tentukan nilai dari g(-5) !

- 51

- 49

Multiple Choice

Diketahui fungsi :

f\left(x\right)=x^2-1

Tentukan nilai dari f(-3) + f(3) !

- 2

- 16

Sekarang, perhatikan cara mencari nilai x pada fungsi !

Next slide

\rightarrow

Jika diketahui fungsi

$f\left(x\right)=4x-2$

Berapa nilai x jika, f(x) = 10 !

Cara :

f\left(x\right)=4x-2

10=4x-2

10+2=4x

12=4x

3=x

Sekarang, latihan soal

Next Slide

\rightarrow

Multiple Choice

Diketahui fungsi :

$f\left(x\right)=2-3x$

Tentukan nilai x, jika f(x) = 8

$-\frac{10}{3}$

$\frac{10}{3}$

- 2

Multiple Choice

Diketahui fungsi :

$f\left(x\right)=-3x-2$

Tentukan nilai x, jika f(x) = - 11 !

- 3

$\frac{13}{3}$

$-\frac{13}{3}$

Multiple Choice

Diketahui fungsi :

$g\left(x\right)=4x+2$

Tentukan nilai x, jika g(x) = - 26 !

- 7

- 6

Multiple Choice

Diketahui fungsi :

$f\left(x\right)=3x-2$ dengan daerah asal $\left\{0,\ 1,\ 2,\ 3,\ 4\right\}$ Tentukan daerah asal nya !

$\left\{-2,\ 1,\ 4,\ 7,\ 10\right\}$

$\left\{-1,\ 1,\ 5,\ 7,\ 10\right\}$

$\left\{-2,\ 3,\ 5,\ 7,\ 11\right\}$

$\left\{0,\ 1,\ 2,\ 3,\ 4\right\}$
