The polynomial function are [tex]x^{2}[/tex] and [tex]\frac{1}{x}[/tex].
A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.
Christi should know the "zeros" of the polynomial function for sketching the graph of it (where the graph intersects with the x an y - axises, (if it does). Also, she needs to know the vertical and horizontal stretches/shrinks for that. Finally, she should know the basic function of the polynomial function such as , [tex]x^{2}[/tex] and [tex]\frac{1}{x}[/tex] , etc.
