Pliss bantuin aku bingung plis bgt harus dikumpulin
Jawaban
1.)
2.)
Penjelasan
1.) f(x) >= 0
12x – 48 >= 0
12x – 48 + 48 >= 0 + 48
12x >= 48
12x/12 >= 48/12
2.) selesaikan y
2xy + 7x = 3y – 4
2xy + 7x – 7x = 3y – 4 – 7x
2xy = 3y – 4 – 7x
2xy – 3y = 3y – 4 – 7x – 3y
2xy – 3y = -4 – 7x
y(2x – 3) = -4 – 7x
cari domain
2x – 3 = 0
2x = 3
2x/2 = 3/2
x = 3/2 (tidak terdefinisi)
