Question #4180f

Answer 1

`c` is the `y`-intercept.

Explanation:

At any value of `a`, if `x=0` then `ax^2=0`. This means that at the point `x=0` (which is on the `y`-axis), the `y` value will always just be `c`.

This is called the `y`-intercept - the point at which the curve crosses the `y`-axis.

If `c` changes, then the graph will move up or down.
