tolong di bantu yaa seberapa mmpu nya saja

1. =3/√2-√3 x √2+√3/√2+√3
= 3(√2-√3)/2-3
=3√2-3√3/-1
= -3√2 + 3√3

2. x^2 -8x+12 =0
(x-2)(x-6)=0
x= 2 atau x = 6

3.range : {a,b,c,d}

4. f(2) = 3(2)^2+2(2)-8
= 3x4 + 4 - 8
= 16 - 8
= 8

5. f(x) = 4, g(x) = x^3-6
f(x)+g(x) = 4 + x^3 - 6 = x^3 -2

6.f(g(x)) = f(x^2-5x) = x^2 - 5x + 2

7.g(f(x)) = 3x
g(x+2) = 3x
misal p = x+2
x = p-2
maka
g(x) = 3(p-2)
g(x) = 3p-6
g(x) = 3x - 6

8.tdk bisa

9. y = 3x+2/3x-2
y(3x-2) = 3x+2
3xy -2y = 3x + 2
3xy -3x = 2y +2
x(3y-3) = 2y+2
x = 2y+2/3y-3
f^-1(x) = 2x+2/3x-3
