Vertical Shifts of Quadratic Functions
Key Questions
-
In order to find the y-intercept
b of any functionf(x) isf(0) .So, the y-intercept of
f(x)=ax2+bx+c isf(0)=a(0)2+b(0)+c=c .The constant term c of a quadratic function is always its y-intercept.
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.

Answer:
Vertical shifts are indicated by a constant added to the base function
x2 , this changes the y-coordinate of the vertex.Explanation:
f(x)=x2+2 moves the function (vertex) up 2 units
f(x)=x2−3 moves the function (vertex) down 3 units
