Respuesta :

to  graph these set of points you put x first (horizontal line) then y second (vertical line) example (-2,10) you would start in the middle then go to the left twice then 10 you go up 10 from that -2 spot

hope i helped you!

Answer:

The quadratic function [tex]Y(x)=3x^2-2[/tex]

Step-by-step explanation:

Graphing those point we can observe that if we joint each point,it has a parabolic form, that is a quadratic model, so:

[tex]y(x)=Ax^2+B[/tex]

When X is zero Y is -2, so:

[tex]-2=A(0)^2+B\\B=-2[/tex]

If we take any point of the set we can obtain the value of A, taking (2, 10) we have:

[tex]10=A(2)^2+(-2)\\A=\frac{12}{4}=3[/tex]

so the function is:

[tex]Y(x)=3x^2-2[/tex]
