Question

Tolong dong jawab nomor 16-18 pakai cara yah please...

Answer 1

16. f(x) = 2x² -4x +3
y = 2x² -4x + 3
memotong sumbu y, jika x = 0
maka,
y = 2(0)² - 4(0) +3
y = 3
hp = (0,3) ----> (e)

17. g(x) = 5-3x
g(a) = 5-3a = -19
-3a = -19-5
a = -24/-3 = 8 ------> (b)

18. f(x) = 2x-10
y = 2x - 10
x = 0, y = -10 >>>>> (0,-10)
y = 0, x = 5 >>>> (5,0)

jawaban : (b)
