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)=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.
