Family of Parabolas y=x²+c: Vertical Shift

Family of Parabolas $y=x²+c$ : Vertical Shift

The basic quadratic function $y=x^2$ with the addition of $C$ yields the function $y=x^2+c$
The meaning of $C$ is the vertical shift of the function upwards or downwards.
If $C$ is positive: the function will rise by the number of steps shown in $C$ .
If $C$ is negative: the function will descend by the number of steps shown in $C$ .

Let's look at an example

$y=x^2+3$
The function will rise three steps.

1 - Vertical shift

Additionally, we can see that $C$ marks the intersection point on the $Y$ axis.
