Which of the following is true about quadratic functions?

• The standard form of a quadratic function is... "y = ax² + bx + c".

• The second differences of the y-values are constant.

• The graph of a quadratic is parabolic.

• All of the above

If a quadratic has 2 solutions, it has ​ (a)   zeroes. If it has 1 solution, it only ​ (b)   the x-axis. (This is called a ​ (c)   root.) If it has ​ (d)   solutions, it never touches the x-axis.
