Question

HELP ASAP!! QUADRATIC FUNCTIONS!! what is the equation in standard form of these points?

Answer 1

Answer:

$-x^2+5x$

Step-by-step explanation:

Let the quadratic be $ax^2+bx+c$. Therefore, if you plug in the first point,

$a(0)^2+b(0)+c=0\\c=0$

and if you plug in the 2 other points,

$a-b=-6\\4a+2b=6$

Multiply the first equation by 2:

$2a-2b=-12$

and add it up to the second equation:

$6a=-6\\a=-1$

Lastly, plug in a for the first equation:

$-1-b=-6\\b=5$

Therefore, the final quadratic is $\boxed{-x^2+5x}$

Answer 2

Y=-x²+5x
