Question 366132
<font face="Garamond" size="+2">


Remember that the points are ordered pairs of the form *[tex \Large (x,y)]


So if *[tex \Large (1,6)] is an element of the solution set of  *[tex \Large y\ =\ ax^2\ +\ bx], then


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ a(1)^2\ +\ b(1)\ =\ a\ +\ b\ =\ 6]


must be a true statement.


Similarly,


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ a(3)^2\ +\ b(3)\ =\ 9a\ +\ 3b\ =\ 6]


must also be a true statement.


Solve the two variable linear system for *[tex \Large a] and *[tex \Large b] to get the specific coefficients for *[tex \Large y\ =\ ax^2\ +\ bx].

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
