Question

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

A. It is NOT a parabola

B. Its vertex is in quadrant III.

c. It is in quadrants I and II.

D. It is NOT a function

Answer 1

C

Explanation:

First, note that the parent quadratic function has the equation
`f(x)=x^2`.

All quadratic functions are parabolas. Eliminate A.

The vertex of
`f(x)=x^2` is on the origin point (0,0), not in Quadrant III. Eliminate B.

`f(x)=x^2` is definitely a function. Eliminate D.

The correct answer is C. The function covers Quadrant I and II.
