Question

SOMEONE PLEASE HELP ME ASAP!!

. Find a quadratic model for the set of values: (-2, -20), (0, -4), (4, -20). Show your work.

Answer 1

its easy
assume the quadratic equation to be y=ax^2 + bx + c
now put the values of the co-ordinates in the place of x and y
there are three co-ordinates
so, you'll get three equations
you have three variables, a, b and c
solve the three equations for three variables
and voila!
you get the quadratic equation

Answer 2

So which of the points are a, b and c?

Answer 3

a,b and c are not points
they are the variables
the points are x and y

Answer 4

ohh okay, thank you :D

Answer 5

you're welcome
but did you really get it??

Answer 6

well thanks for the medal

Answer 7
