Question

Which of the following is a key property of the quadratic parent function?

A.) It is a parabola

B.) It is not a function

C.) Its vertex is not at the origin

D.) It is in quadrants III and IV

Answer 1

The graph of any quadratic function is referred to as a parabola.

1. Equation: y = x²
2. Domain: All real numbers
3. Range: All real numbers greater than or equal to 0. (y ≥ 0)
4. y-intercept: (0,0)
5. x-intercept: (0,0)
6. Line of symmetry: (x = 0)
7. Vertex: (0,0)

So option A is correct.
