amistre64 · Answer

i made this for this kinda problem; just gotta plug in the numbers in reverse tho for this one

anonymous · Answer

what level of math are you in?

amistre64 · Answer

0.25y^2 -9.25y  + 76 maybe

anonymous · Answer

I think you need a system of linear equations to solve this problem

amistre64 · Answer

yeah, you do :)

amistre64 · Answer

3 of them

anonymous · Answer

I think that you can find the reduced row echelon form of the system or use craemers rule

anonymous · Answer

sorry if you do not understand reduced row echelon form... it is fancy matrix math I learned in a college linear algebra class

anonymous · Answer

I think you just need to choose 3 sample points. If you use all 5 you will have an overdetermined system.

anonymous · Answer

we have to figure it out by refering to the parent function which is y=x^2
