Jawaban :

1. x = 25

2. g(6) = 2

3. x = 6

4. c = 15

5. f(-3) = 4

Penjelasan dengan langkah–langkah :

$f(x) = frac{1}{3} (x - 4) \ 7 = frac{1}{3} (x - 4) \ 7 = frac{1}{3} x - frac{4}{3} \ 7 + frac{4}{3} = frac{1}{3} x \ frac{21 + 4}{3} = frac{1}{3} x \ frac{25}{3} div frac{1}{3} = x \ frac{25}{3} times frac{3}{1} = x \ 25 = x$

2. g(x) = px + b

g(5) = 5p + b = 0

g(7) = 7p + b = 4

———————— –

-2p. = -4

p. = -4 ÷ (-2)

p = 2

subtitusi p = 5(2) + b = 0

= 10. + b = 0

b = 0 – 10

b = -10

g(x) = 2x + (-10)

g(6) = 2(6) + (-10)

g(6) = 12 – 10

g(6) = 2

3. f(x) = 16 – x

10 = 16 – x

x = 16 – 10

x = 6

4. f(x) = 2x – c

f(3) = 2(3) – c

-9. = 6 – c

c = 6 + 9

c = 15

5. f(x) = ax + b

f(1) = 1a + b = -8

f(4) = 4a + b = -17

————————- –

-3a. = 9

a. = 9 ÷ (-3)

a. = -3

subtitusi a = 1(-3) + b = -8

= -3. + b = -8

b = -8 + 3

b = -5

f(x) = -3x – 5

f(-3) = -3(-3) – 5

f(-3) = 9. – 5

f(-3) = 4

semoga membantu
