Question

Graph the set of points. Which model is most appropriate for the set?

Answer 1

Answer:

The quadratic function $Y(x)=3x^2-2$

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:

$y(x)=Ax^2+B$

When X is zero Y is -2, so:

$-2=A(0)^2+B\\B=-2$

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

$10=A(2)^2+(-2)\\A=\frac{12}{4}=3$

so the function is:

$Y(x)=3x^2-2$

Answer 2

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!
