Graphing Functions

The parent function for a parabolic function is ${\displaystyle f(x)=a(x-<!--\; -\; -->h{)}^2+k}$ where ${\displaystyle (h,k)}$ is the center of the parabola. To shift the parabola left of right, the value of h changes. Since there is a negative sign in the parent function, a positive value moves the parabola to the left and a negative value moves it to the right.
