2.3 Quadratic Functions - Sam Houston State University

188 Linear and Quadratic Quadratic FunctionsYou may recall studying Quadratic equations in Intermediate Algebra. In this section, we reviewthose equations in the context of our next family of Functions : the Quadratic functionis a function of the formf(x) =ax2+bx+c,wherea,bandcare real numbers witha6= 0. The domain of a Quadratic function is ( , ).The most basic Quadratic function isf(x) =x2, whose graph appears below. Its shape should lookfamiliar from Intermediate Algebra it is called aparabola. The point (0,0) is called thevertexof the parabola. In this case, the vertex is a relative minimum and is also the where the absoluteminimum value offcan be found.( 2,4)( 1,1)(0,0)(1,1)(2,4)xy 2 1121234f(x) =x2 Much like many of the absolute value Functions in Section , knowing the graph off(x) =x2enables us to graph an entire family of Quadratic Functions using the following Functions starting with the graph off(x) =x2and usingtransformations.
