Tolong di jawab ya !! Menggunakan caranya(jalannya). Nanti sikumpul jam 11.00

1.
domain = daerah asal fungsi
kodomain = daerah tujuan fungsi
range = hasil fungsi

2.
domain = 4
kodomain = 4
korespondensi 1 1 = 4 x 4 = 16

3.
daerah asal
{-1, 0, 1, 2, 3, 4}
f(x) = 2x + 5
f(-1) = 3
f(0) = 5
f(1) = 7
f(2) = 9
f(3) = 11
f(4) = 13

4.
f(½) = 2(½)² – 2(½) – 12
= 2 * ¼ – 1 – 12
= ½ – 1 – 12
= -12,5

5.
f(x) = mx + n
f(2) = -1
2m + n = -1
f(3) = 2
3m + n = 2

3m + n = 2
2m + n = -1
————- –
m = 3

3m + n = 2
9 + n = 2
n = -7
