Quadratic means 2nd degree
I'm thinking

y=ax²

when x=2, y=2
when x=4, y=8

so

2=a2² and
8=a4² or

2=4a and
8=16a
easy
divide first equation by 4 and 2nd by 16 to get

1/2=a

then

y= \frac{1}{2}x^2



A. I would say 1/2 is constant
B. isy= \frac{1}{2}x^2

(12y2<br> + 17y - 4) + (9y2<br> - 13y + 3) =
Anna [14]

Answer:

21y^{2} +4y-1

Step-by-step explanation:

Hello!

(12y^{2} +17y-4)+(9y^{2} -13y+3)

For this, we can combine like terms

12y^{2} +9y^{2}=21y^{2}

17y - 13y = 4y

-4 + 3 = -1

Combine the answers and we get

21y^{2} +4y-1

Hope this Helps!
