Parent Functions. Here we sketch two parent functions: y=k (some constant k) and y=x (the linear function) This seven video series shows sketches of the ten most common parent functions. endobj Quadratic functions generally have the whole real line as their domain: any x is a legitimate input. The domain, range, x-intercept, and y-intercept of the ten parent functions in Algebra 2. The function tells us which y in the range goes with each x in the domain. Graphs of eight basic parent functions are shown below. The domain of a function is the set of input values, [latex]x[/latex], for which a function is defined.

It's a first-degree equation that's written as y = x. In interval notation, this is written as [c,c] [ c, c], the interval that both begins and ends with c c. With a constant function, for any two points in the interval, a change in x results in a zero change in f (x). �(P�����{?t� �Y��,a�p�P����ަ�,�}j�2�j.d�>��o.�zT���P�Bwn��q�jg���$�3HB�(�>U.�Q��k��r�/�V��������1-�1�������}"��WEUH�e@R GrD0垐�hPZ!R�Fl�"h-�� �m�`Q�x7�kJ��(�m�� � Zh5���"��5���8�S�H_�W��ߡ�/P�+�����48c�We*�$Q�\�=��3���e�>���l�ϵ��ܢ��;oe��*1���J�4��r0���r�r@7xG���[zN��s�[7�A� The only output value is the constant c c, so the range is the set {c} { c } that contains this single element. %���� Graphs of Domain and Range of Functions.
