Question

Bantu saya menjawab soal nomor enam sampai soal nomor sepuluh.terimakasih

Answer 1

6) f(x) = px + q
f(3) = 3p + q = 5
f(1) = p + q = 3
----------------------(-)
2p = 2
p = 1
p + q = 3
1 + q = 3
q = 3 - 1 = 2
b) f(x) = x + 2
c) f(-3) = (-3) + 2 = (-1)
f(6) = 6 + 2 = 8

7) f(x) = x² - 9
f(-2) = (-2)² - 9 = (-5)
f(-1) = (-1)² - 9 = (-8)
f(0) = 0² - 9 = (-9)
f(1)² = 1 - 9 = (-8)
f(2) = 2² - 9 = 4 - 9 = (-5)
f(3) = 3² - 9 = 9 - 9 = 0

8) f(x) = 3x + 5
f(x - 1) = (3x + 5) - 1
= 3x + 5 - 1
= 3x + 4
f(2x + 3) = 2(3x + 5) + 3
= 6x + 10 + 3
= 6x + 13

9) p(t) = 3t - 5
a) p(4) = 3.4 - 5 = 7
p(1) = 3.1 - 5 = (-2)
p(-2) = 3.(-2) - 5 = (-11)
p(-14) = 3(-14) - 5 = (-47)
b) p(t) = 3t - 5 = 97
3t = 97 + 5
3t = 102
t = 34
t + 6 = 34 + 6 = 40
