1. Jawaban aivko
a) f(x) = 2x
* f(1) = 2 x 1 * f(3) = 2 x 3
= 2 = 6
* f(2) = 2 x 2 * f(4) = 2 x 4
= 4 = 8
b) f(x) = -x
* f(5) = -5 * f(7) = -7
* f(6) = -6 * f(8) = -8
c) f(x) = x + 3
* f (-1) = -1 + 3 * f (1) = 1 + 3
= 2 = 4
* f (0) = 0 + 3 * f (2) = 2 + 3
= 3 = 5
* f (3) = 3 + 3
= 6
d) f(x) = x² + 1
* f(1) = 1² + 1 * f(3) = 3² + 1
= 1 + 1 = 2 = 9 + 1 = 10
* f(2) = 2² + 1
= 4 + 1 = 5
e) f(x) = 2x² - 10
* f(-2) = 2.(-2²)- 10 = 2 x 8 - 10 = 6
* f(-1) = 2.(-1) - 10 = 2 - 10 = -8
* f(0) = 2.0 - 10 = 0 - 10 = -10
* f(1) = 2.1 - 10 = 2 - 10 = -8
* f(2) = 2.2 - 10 = 4 - 10 = -6
