Answer:
f(-9) = -263
Step-by-step explanation:
f(-9) = -3(-9)^2 - 20
= -3(81) - 20
= -243 - 20
= -263
➪-263
-3x²-20
-3(-9)²-20
-3(81)-20
-243-20
-263
nice same here but im NOT mingling with you
Intersept is (4.55,0)
1/2, 1/3, 1/4, 1/5, 1/6
a2 – b2 = (a – b)(a + b)
(a + b)2 = a2 + 2ab + b
a2 + b2 = (a + b)2 – 2ab
(a – b)2 = a2 – 2ab + b
That's all i know- rip TvT
