5. fungsi f di definisikan dengan rumus f(×) =10-4× tentukan :

Jawaban:

f(x) = 10 – 4x => rumus fungsi

# Soal A

=> bayangan dari -2, 0, 2, dan 4?

f(-2) = 10 – 4(-2)

= 10 + 8

= 18

f(0) = 10 – 4(0)

= 10

f(2) = 10 – 4(2)

= 10 – 8

= 2

f(4) = 10 – 4(4)

= 10 – 16

= -6

# Soal B

=> Nilai y jika, f(y) = 14

10 – 4y = 14

-4y = 14 – 10

-4y = 4

y = 4/-4

y = -1

# Soal C

=> Nilai m, jika f(m) = -10

10 – 4m = -10

-4m = -10 – 10

-4m = -20

m = -20/-4

m = 5
