Write the equation of the parabola in standard form that passes through the points (2,7),(-1,10), and (0,5) help me please! I don't remember how to do this and I have a test tomorrow

$\displaystyle a(2)^2 + b(2) + c = 7$ $\displaystyle a(-1)^2 + b(-1) + c = 10 $ $\displaystyle a(0)^2 + b(0) + c = 5$ solve the system for the coefficients a, b, and c
and then plot what value you get for the x value you plug in?
When you get a,b,c you can write the equation in the form $\displaystyle ax^2 +bx +c$. That would be the equation of a parabola.
