Answer:
can you please give me an example?
i will help you but give me your teacher's example
Step-by-step explanation:
let me know if it's done
I think it's D. I will admit that I'm an educated guess.
[(14,7 + 5,9) x 5,8] / 2 = 59,74 cm^2
Y = -2x^2
h = Xv = -B/2A = 0/-4 = 0.
k = -2*0^2 = 0.
V(0,0).
Use the following points for graphing:
Y = -2x^2.
(x,y)
(-2,-8)
(-1,-2)
V(0,0)
(1,-2)
(2,-8)
Y = -2x^2 + 4.
h = Xv = -B/2A = 0/-4 = 0.
k = Yv = -2*0^2 + 4 = 4.
V(0,4).
(-2,-4)
(-1,2)
V(0,4)
(1,2)
(2,-4)
