Chapter 2.2, Problem 42E
To determine

To sketch : The graph of the given function.

Expert Solution

Explanation of Solution

Given information :

  f(x)={1x2    if  x2x           if  x>2

Graph :

    x31012345
    f(x)80103345

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 2.2, Problem 42E

This is the graph of the given piecewise defined equation.

Interpretation : The part of the graph to the left of x=2 coincides with the graph of f(x)=1x2 and the part of the graph to the right of x=2 coincides with the graph of f(x)=x . The open dot at (2,2) indicates that this point is excluded from the graph.
