now that you know the vertex of each you can write the vertex form of each of the equation

wait why is f(x)=x^2+2= x^2? shouldn't it be just f(x)=x^2?

the main form is f(x)=x^2 but if you change them to y=x^2 now theres a negative sign then if you add 2 then you have to jump up 2 on y axis

did you see the difference between the two graph now?
