find the inverse of the function
\n" ); document.write( "f(x)= 4 sqrt(-5x+2)+3
\n" ); document.write( "-----
\n" ); document.write( "1st: Interchange x and y:::
\n" ); document.write( "x = 4*sqrt(-5y+2)+3
\n" ); document.write( "-----
\n" ); document.write( "2nd: Solve for \"y\":
\n" ); document.write( "4*sqrt(-5y+2) = x-3
\n" ); document.write( "-----
\n" ); document.write( "sqrt(-5y+2) = (x-3)/4
\n" ); document.write( "-----
\n" ); document.write( "-5y+2 = (x^2-6x+9)/16
\n" ); document.write( "-----
\n" ); document.write( "-5y = (x^2-6x+9)/16 - 2
\n" ); document.write( "----
\n" ); document.write( "y = -(x^2-6x+9)/80 - (2/5)
\n" ); document.write( "etc.
