pernyataan yg salah yg C
semoga membantu
-6≤x≤2, -4≤y≤3
xy :
(-6).(-4) ? xy ? 2.3
24≥xy≥6 <= maksimum xy = 24
minimum xy = -6.3 = -18
x+y :
-6+(-4) ≤ x+y ≤ 2+3
-10 ≤ x+y ≤ 5 <= maksimum x+y = 2+3 = 5, minimum x+y = -10
x - y :
-6-(-4) ≤ x-y ≤ 2-3
-2 ≤ x-y ≤ -1 <= maksimum x-y = 2-(-4) = 6
minimum x-y = -6-(-4) = -2
yang C
