Find the inverse of f(x)= 2tan(x - 1) + 3.
\n" ); document.write( "Interchange x and y; then solve for \"y\":
\n" ); document.write( "x = 2tan(y-1)+3
\n" ); document.write( "(x-3)/2 = tan(y-1)
\n" ); document.write( "----
\n" ); document.write( "y-1 = arctan[(x-3)/2]
\n" ); document.write( "---
\n" ); document.write( "f^-1(x) = arctan[(x-3)/2]+1
\n" ); document.write( "----
\n" ); document.write( "Domain of f^-1: All Real Numbers
\n" ); document.write( "Range of f^-1: All Real Numbers
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "f(x) = 2*tan(x-1)+3
\n" ); document.write( "Domain: All Real Numbers
\n" ); document.write( "Range: All Real Numbers
