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.

The correct answer is B) the graph is symmetrical about the y-axis.

The graph cannot be folded around the x-axis.
The domain is the set of all real numbers, as any number for x can give us a y-value.
The range is not the set of all real numbers, because there will be some y-values that we do not get from the function.
