diketahui f(x)=2x+3 dengan domain {x/-3

Dik : f(x) = 2x + 3
D = -3, -2, -1, 0, 1, 2, 3

Jb :
f(x) = 2x + 3
* f(-3) = 2 (-3) + 3
= -6 + 3 = -3

* f(-2) = 2 (-2) + 3
= -4 + 3 = -1

* f(-1) = 2 (-1) + 3
= -1 + 3 = 2

* f(0) = 2 (0) + 3
= 0 + 3 = 3

* f(1) = 2 (1) + 3
= 2 + 3 = 5

* f(2) = 2 (2) + 3
= 4 + 3 = 7

* f(3) = 2 (3) + 3
= 6 + 3 = 9

x : -3, -2, -1, 0, 1, 2, 3
y : -3, -1, 2, 3, 5, 7, 9
