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.

Correct sir/miss have a good day x < 3
