curve line
i have points of (25,43)

so i would put the point in like this

43=A(25)^3+B(25)^2+C(25)+D

the question is if im doing it right

cuz i have 4 points and i have to get the points to go into the equation

$y=ax^2+bx+c$

or something like that

Can you write down the question for me? It will be easier for me to answer if you wrote it out.

Thanks.

there kinda is no question on a sheet, i had to print out this building onto grapg paper and then find a curved live and put 4 points on

the 4 points are:
a) (25, 43)
b) (28, 46)
c) (32, 47)
d) (35, 45)

i have to put them into quadratic for, general form, and standard form

so thats what im workin with

If you didn't graph the the points already then you should do that. But if you did already then what you did is correct. All you do is plug in the x points into the quadratic form as you did above.
