Question

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

Answer 1

Answer:

C

Step-by-step 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.
