Question

Which statement about the quadratic parent function is true?

Answer 1

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

A quadratic graph cannot be "folded" across the x-axis.
The domain, or set of inputs, is all real numbers; there is no value of x for which there will be no y.
The range, or set of outputs, is not all real numbers; there are values of y that will not be used in the graph.
