4. Which statement about the quadratic parent function is true?

A) Its graph is symmetrical about the x-axis.

B) Its graph is symmetrical about the y-axis.

C) Its domain is the set of all non-negative numbers.

D)Its range is the set of all real numbers.

Answer: B) Its graph is symmetrical about the y-axis.

The quadratic parent function, 𝑓(𝑥)=𝑥2f(x)=x2, is symmetrical about the y-axis. This means that if you were to fold the graph along the y-axis, the two sides would coincide perfectly.
