For the function f(x) represented as y=x^2-4.
\n" ); document.write( "A) How do I write the equation defining the inverse of f(x)
\n" ); document.write( "1st: Interchange x and y to get:
\n" ); document.write( "x = y^2-4
\n" ); document.write( "2nd: Solve for \"y\":
\n" ); document.write( "y^2 = x+4
\n" ); document.write( "y = +-sqrt(x+4)
\n" ); document.write( "-------------------------------
\n" ); document.write( "B) How do I sketch the graphs of f and its inverse relation on the same axes?
\n" ); document.write( "
\n" ); document.write( "------------------------------------------------------
\n" ); document.write( "C) How do I state whether the inverse relation is a function?
\n" ); document.write( "It is not because there are x values in the domain of f^-1(x) that
\n" ); document.write( "have 2 associated y-values.
