Vertical Shifts of Quadratic Functions
Key Questions

In order to find the yintercept
#b# of any function#f(x)# is#f(0)# .So, the yintercept of
#f(x)=ax^2+bx+c# is#f(0)=a(0)^2+b(0)+c=c# .The constant term c of a quadratic function is always its yintercept.
I hope that this was helpful.

I would start with its vertex, then move either to the right or to the left, then use a symmetry to draw the other half.
I hope that this was helpful.

Answer:
Vertical shifts are indicated by a constant added to the base function
#x^2# , this changes the ycoordinate of the vertex.Explanation:
#f(x)=x^2+2# moves the function (vertex) up 2 units
#f(x)=x^23# moves the function (vertex) down 3 units
