tolong bantuuuuu sayaaa:((

1.
rumus fungsi nya g(x) = 3x - 1

2.
h(x) = 6 - 2x

h(4) = 6 - 2(4)
h(4) = 6 - 8
h(4) = -2

bayangan dari 4 adalah -2

3.
n(A) = 4
n(B) = 2
banyaknya pemetaan yg mungkin dr A ke B
b^a = 2⁴ = 16

4.
g(x) = x² - 5
domain {-1, 0, 1}
g(-1) = (-1)² - 5 = -4
g(0) = 0²- 5 = -5
g(1) = 1²- 5 = -4
daerah hasil {-5, -4}

5.
f(x) = 5x - 2
f(a) = 5a - 2
5a - 2 = 8
5a = 8 + 2
5a = 10
a = 10/5
a = 2
