We can see that, in this case, that, for each value of x, we get the square of x for y.
Then, we can say that:
[tex]x=-1\Rightarrow(-1)\cdot(-1)=1_{}[/tex][tex]x=2\Rightarrow2\cdot2=4,x=3\Rightarrow3\cdot3=9[/tex]
And we also get the same result for x =0 and x = 1.
Then, this is a quadratic function, since the quadratic function is of the form:
[tex]y=nx^2[/tex]
In this case, then, the parent function, that is, the function that any of the quadratic function coming from is:
[tex]y=x^2[/tex]
Which is the parent function (and even the function in this case).
