Ican't figure this out
this question was on my exam and i got it completely wrong
(i have a graphing calculator capble of matrices so yo don't have to solve the system of equations by hand, use rref (reduced row echelon form))
values of a, b, and c and the equation of the graph of the parabola
y=ax^2+bx+c
such that is passes through the points
(2,-15)
(-5,-29)
(-3,5)
rewrite it in the form (x-h)^2=4p(y-k)
show all work
if i were to sub the points in i would ge
(2,-15): -15=4a+2b+c
(-5,-29): -29=25a-5b+c
(-3,5): 5=9a-3b+c
then solve for a, b and c
i don't know how to solve,
(if i don't undestand your answer, i will either report or ask you to explain more)
