Concept explainers
To graph: The function and label the vertex and axis of symmetry.
Given information:
The function is
Graph:
The steps followed for graphing the function of the form
Step-1: Find coefficients
Step-2: Find vertex
Thus, the vertex of the parabola represented by the function
Step-3: The equation of the axis of symmetry (line) is
Step-4: Find other points
Step-5: Plot axis of symmetry, vertex and other points. The points table and the graph of the function is shown in Fig. (1).
Interpretation:
The axis of symmetry divides the area of the region bounded by the curve into two equal parts.
The vertex of the graph of a function is a point where curve bends making this point a lowest or highest point in the curve where maxima or minima of the function exists.
